## 20 Grade-School Math Questions So Hard You'll Wonder How You Graduated

Unless you grew up to be an engineer, a banker, or an accountant, odds are that elementary and middle school math were the bane of your existence. You would study relentlessly for weeks for those silly standardized tests—and yet, come exam day, you'd still somehow have no idea what any of the equations or hard math problems were asking for. Trust us, we get it.

While logic might lead you to believe that your math skills have naturally gotten better as you've aged, the unfortunate reality is that, unless you've been solving algebra and geometry problems on a daily basis, the opposite is more likely the case.

Don't believe us? Then put your number crunching wisdom to the test with these tricky math questions taken straight from grade school tests and homework assignments and see for yourself.

### 1. Question: What is the number of the parking space covered by the car?

This tricky math problem went viral a few years back after it appeared on an entrance exam in Hong Kong… for six-year-olds. Supposedly the students had just 20 seconds to solve the problem!

### Answer: 87.

Believe it or not, this "math" question actually requires no math whatsoever. If you flip the image upside down, you'll see that what you're dealing with is a simple number sequence.

### 2. Question: Replace the question mark in the above problem with the appropriate number.

This problem shouldn't be *too* difficult to solve if you play a lot of sudoku.

### Answer: 6.

All of the numbers in every row and column add up to 15! (Also, 6 is the only number not represented out of numbers 1 through 9.)

### 3. Question: Find the equivalent number.

This problem comes straight from a standardized test given in New York in 2014.

### Answer: 9.

You're forgiven if you don't remember exactly how exponents work. In order to solve this problem, you simply need to subtract the exponents (4-2) and solve for 3^{2}, which expands into 3 x 3 and equals 9.

### 4. Question: How many small dogs are signed up to compete in the dog show?

This question comes directly from a second grader's math homework. Yikes.

### Answer: 42.5 dogs.

In order to figure out how many small dogs are competing, you have to subtract 36 from 49 and then divide that answer, 13, by 2, to get 6.5 dogs, or the number of big dogs competing. But you're not done yet! You then have to add 6.5 to 36 to get the number of small dogs competing, which is 42.5. Of course, it's not actually possible for half a dog to compete in a dog show, but for the sake of this math problem let's assume that it is.

### 5. Question: Find the area of the red triangle.

This question was used in China to identify gifted 5th graders. Supposedly, some of the smart students were able to solve this in less than one minute.

### Answer: 9.

In order to solve this problem, you need to understand how the area of a parallelogram works. If you already know how the area of a parallelogram and the area of a triangle are related, then adding 79 and 10 and subsequently subtracting 72 and 8 to get 9 should make sense—but if you're still confused, then check out this YouTube video for a more in-depth explanation.

### 6. Question: How tall is the table?

YouTuber MindYourDecisions adapted this mind-boggling math question from a similar one found on an elementary school student's homework in China.

### Answer: 150 cm.

Since one measurement includes the cat's height and subtracts the turtle's and the other does the opposite, you can essentially just act like the two animals aren't there. Therefore, all you have to do is add the two measurements—170 cm and 130 cm—together and divided them by 2 to get the table's height, 150 cm.

### 7. Question: If the cost of a bat and a baseball combined is $1.10 and the bat costs $1.00 more than the ball, how much is the ball?

This problem, mathematically speaking, is very similar to one of the other ones on this list.

### Answer: $0.05.

Think back to that problem about the dogs at the dog show and use the same logic to solve this problem. All you have to do is subtract $1.00 from $1.10 and then divide that answer, $0.10 by 2, to get your final answer, $0.05.

### 8. Question: When is Cheryl's birthday?

If you're having trouble reading that, see here:

"Albert and Bernard just became friends with Cheryl, and they want to know when her birthday is. Cheryl gives them a list of 10 possible dates.

May 15 May 16 May 19

June 17 June 18

July 14 July 16

August 14 August 15 August 17

Cheryl then tells Albert and Bernard separately the month and the day of her birthday respectively.

Albert: I don't know when Cheryl's birthday is, but I know that Bernard doesn't not know too.

Bernard: At first I don't know when Cheryl's birthday is, but I know now.

Albert: Then I also know when Cheryl's birthday is.

So when is Cheryl's birthday?"

It's unclear why Cheryl couldn't just tell both Albert and Bernard the month and day she was born, but that's irrelevant to solving this problem.

### Answer: July 16.

Confused about how one could possibly find any answer to this question? Don't worry, so was most of the world when this question, taken from a Singapore and Asian Schools Math Olympiad competition, went viral a few years ago. Thankfully, though, the *New York Times* explains step-by-step how to get to July 16, and you can read their detailed deduction here.

### 9. Question: Find the missing letter.

This one comes from a *first grader's *homework.

### Answer: The missing letter is J.

When you add together the values given for S, B, and G, the sum comes out to 40, and making the missing letter J (which has a value of 14) makes the other diagonal's sum the same.

### 10. Question: Solve the equation.

This problem might look easy, but a surprising number of adults are unable to solve it correctly.

### Answer: 1.

Start by solving the division part of the equation. In order to do that, in case you forgot, you have to flip the fraction and switch from division to multiplication, thus getting 3 x 3 = 9. Now you have 9 – 9 + 1, and from there you can simply work from left to right and get your final answer: 1.

### 11. Question: Where should a line be drawn to make the below equation accurate?

5 + 5 + 5 + 5 = 555.

### Answer: A line should be drawn on a "+" sign.

When you draw a slanted line in the upper left quadrant of a "+," it becomes the number 4 and the equation thusly becomes 5 + 545 + 5 = 555.

### 12. Question: Solve the unfinished equation.

Try to figure out what all of the equations have in common.

### Answer: 4 = 256.

The formula used in each equation is 4^{x }= Y. So, 4^{1 }= 4, 4^{2 }= 16, 4^{3 }= 64, and 4^{4} = 256.

### 13. Question: How many triangles are in the image above?

When *Best Life *first wrote about this deceiving question, we had to ask a mathematician to explain the answer!

### Answer: 18.

Some people get stumped by the triangles hiding inside of the triangles and others forget to include the giant triangle housing all of the others. Either way, very few individuals—even math teachers—have been able to find the correct answer to this problem. And for more questions that will put your former education to the test, check out these 30 Questions You'd Need to Ace to Pass 6th Grade Geography.

### 14. Question: Add 8.563 and 4.8292.

Adding two decimals together is easier than it looks.

### Answer: 13.3922.

Don't let the fact that 8.563 has fewer numberrs than 4.8292 trip you up. All you have to do is add a 0 to the end of 8.563 and then add like you normally would.

### 15. Question: There is a patch of lily pads on a lake. Every day, the patch doubles in size…

… If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake?

### Answer: 47 days.

Most people automatically assume that half of the lake would be covered in half the time, but this assumption is wrong. Since the patch of pads *doubles* in size every day, the lake would be half covered just one day before it was covered entirely.

### 16. Question: How many feet are in a mile?

This elementary school-level problem is a little less problem solving and a little more memorization.

### Answer: 5,280.

This was one of the questions featured on the popular show *Are You Smarter Than a 5th Grader?*

### 17. Question: What value of "x" makes the equation below true?

-15 + (-5x) = 0

### Answer: -3.

You'd be forgiven for thinking that the answer was 3. However, since the number alongside x is negative, we need x to be negative as well in order to get to 0. Therefore, x has to be -3.

### 18. Question: What is 1.92 divided by 3?

You might need to ask your kids for help on this one.

### Answer: 0.64.

In order to solve this seemingly simple problem, you need to remove the decimal from 1.92 and act like it isn't there. Once you've divided 192 by 3 to get 64, you can put the decimal place back where it belongs and get your final answer of 0.64.

### 19. Question: Solve the math equation above.

Don't forget about PEMDAS!

### Answer: 9.

Using PEMDAS (an acronym laying out the order in which you solve it: "parenthesis, exponents, multiplication, division, addition, subtraction"), you would first solve the addition inside of the parentheses (1 + 2 = 3), and from there finish the equation as it's written from left to right.

### 20. Question: How many zombies are there?

Finding the answer to this final question will require using fractions.

### Answer: 34.

Since we know that there are two zombies for every three humans and that 2 + 3 = 5, we can divide 85 by 5 to figure out that in total, there are 17 groups of humans and zombies. From there, we can then multiply 17 by 2 and 3 and learn that there are 34 zombies and 51 humans respectively. Not too bad, right?

Again fill the 3Lt bottle. Now pour 2 litres into the 5Lt bottle until it becomes full.

Now empty 5Lt bottle.

Pour remaining 1 litre in 3Lt bottle into 5Lt bottle.

Now again fill 3Lt bottle and pour 3 litres into 5Lt bottle.

Now you have 4 litres in the 5Lt bottle. That’s it.

Solution 2 :

First, fill the 5Lt bottle and pour 3 litres into 3Lt bottle.

Empty 3Lt bottle.

Pour remaining 2 litres in 5Lt bottle into 3Lt bottle.

Again fill the 5Lt bottle and pour 1 litre into 3 Lt bottle until it becomes full.

Now you have 4 litres in the 5Lt bottle. That’s it.

**3 Friends went to a shop and purchased 3 toys. Each person paid Rs.10 which is the cost of one toy. So, they paid Rs.30 i.e. total amount. The shop owner gave a discount of Rs.5 on the total purchase of 3 toys for Rs.30. Then, among Rs.5, Each person has taken Rs.1 and remaining Rs.2 given to the beggar beside the shop. Now, the effective amount paid by each person is Rs.9 and the amount given to the beggar is Rs.2. So, the total effective amount paid is 9*3 = 27 and the amount given to beggar is Rs.2, thus the total is Rs.29. Where has the other Rs.1 gone from the original Rs.30?**

**Answer: **

The logic is payments should be equal to receipts. We cannot add the amount paid by persons and the amount given to the beggar and compare it to Rs.30.The total amount paid is ₹27. So, from ₹27, the shop owner received 25 rupees and beggar received ₹ 2. Thus, payments are equal to receipts.

**Conclusion**

**Conclusion**The ultimate goals of mathematics instruction are students understanding the material presented, applying the skills, and recalling the concepts in the future. There's little benefit in students recalling a formula or procedure to prepare for an assessment tomorrow only to forget the core concept by next week.

Teachers must focus on making sure that the students understand the material and not just memorize the procedures. After you learn the answers to a fun maths question, you begin to ask yourself how you could have missed something so easy. The truth is, most trick questions are designed to trick your mind, which is why the answers to fun maths questions are logical and easy.

## 15 tricky children's test questions that stumped the internet

- Math is hard — but sometimes it's so hard, even parents are stumped when trying to help their children with their homework.
- Sometimes, equations that stumped parents and the internet are just plain wrong.
Visit Insider's homepage for more stories.

Homework is designed to challenge students, or, at the very least, reinforce what they learned during the school day. But sometimes these questions go a little too far in terms of difficulty (or they're just plain wrong), forcing confused parents to ask the internet for help.

Check out these children's homework questions that even adults couldn't figure out without a little help from the worldwide web.

### First graders were expected to solve this problem in 20 seconds.

This problem has been around for a while, but recently resurfaced on an elementary school entrance exam in Hong Kong. Apparently, six year olds were expected to know the answer in 20 seconds or less.

There's something fun about this math problem — it requires no math! Just turn the question upside down, and you'll see that it's just a simple number sequence, with the answer being 87.

### Parents are split between two answers on this question for second graders.

A UK mom tweeted this math problem in a since-deleted tweet saying "Have you seen this one? Year 2!!" It was then picked up by a Facebook page called Parents Against Primary Testing and media outlets like The Huffington Post.

Calculating the answer is simpler than it seems: 19 people getting off the train can be represented by -19, and 17 people getting on the train as +17.

-19 + 17 = 2, meaning that there was a net loss of two people. If there are 63 people on the train now, that means there were 65 to begin with.

That said, many are convinced the answer is 46.

Here's a full explanation of the answer.

### This homework question for third graders is simply too ambiguous.

This is *way* too vague to be an acceptable question. All the problem states is that Janell lost "some" of her marbles. There is literally no way to know how many she has now.

When the problem hit Reddit, a wealth of answers came flooding in, including "some," "15 - n {n ∈ ℤ | 1

The simplest answer is < 15, but even that is a little abstract for a third grader.

### This type of problem is known as a petite circle sum, and this one is meant for first graders.

This question appeared on Twitter, where a user said it was for first graders in Singapore.

This type of question is known as a petite circle sum. The numbers in the four sections should be equal to the sum of the three numbers in the circles touching that section. Numbers in circles can't be higher than a nine, and only used once.

Some people said there was a typo and that the two should be a 20, while others claimed they had figured it out with the numbers given. While definitely tough for a first grader, an explanation that circled the internet supports the typo theory.

### Known as "Cheryl's Birthday," this is one of the most famous homework questions in the world.

Kenneth Kong, a television host in Singapore, shared a photo of this 9th grade-level math question in a since-deleted Facebook post, which was shared nearly 6,000 times.

In the logic puzzle, Cheryl gives her friends Albert and Bernard different clues as to when her birthday is out of a selection of dates. She tells Albert only the day and Bernard only the month of her birthday.

By making a table of the dates and using the process of elimination, one can determine that Cheryl's birthday is July 16.

It was later revealed that this problem wasn't a regular test question used in Singapore classrooms. It was actually used in a contest as part of the Singapore and Asian Schools Math Olympiad (SASMO).

The New York Times published a detailed explanation of the solution, which you can read here.

### The wording of this question is confusing.

This picture was posted on Reddit, with the caption "The American education system."

There are two things that are confusing about this question. One, the wording implies that it *is *possible for Marty to eat more than Luis. Two, it's never specified whether the pizzas are the same size or not, so the student is technically right. Thus, the teacher is wrong, because there *are *situations where it is possible.

### This math question in Vietnam isn't that difficult, but extremely time consuming.

The challenge: use each digit 1-9 only once to fill in the snake and make the equation equal 66 (colons are division signs).

According to VNEXPRESS, this puzzle is meant for third graders. There's no trick or complicated math necessary — finding the correct configuration of numbers comes down to trial and error and process of elimination.

A comment thread on a Guardian article has over 1,000 comments from people trying to figure out how to solve this question.

Eventually, there was an post explaining how to solve the puzzle, which involved a *lot *of trial and error.

### This problem caused controversy.

After this tweet unexpectedly went viral, people were quick to assume that there had been some sort of mistake. If it takes 120 people to play a 40-minute song, how long would it take 60 people to play the same song?

If you said 80 minutes, you're among the majority, but still wrong. A song is 40 minutes no matter how many people are playing it.

The original author of the question explained that it was just a trick question to keep her students on their toes.

### Not even kindergarten students are safe from impossible homework questions.

Since the first three answers start with a "t," wouldn't it make sense for the last picture to also start with a "t?" Maybe, but what if there's no t-word that makes sense? Royce Winnick posted this picture on Facebook to ask for help with her daughter's homework, and got suggestions like "twins," "twabbit,"and "this was an error."

The real answer? Vet, which is a stretch, and also doesn't start with a t.

### A family had to ask Facebook for help with their first grader's homework.

Mathematics puzzles are fun, interesting, and nerve-wracking at the same time. Most of the students are afraid of Maths and as teachers, if you include tricky Maths puzzles, this will help in inculcating an interest in the subject. Parents can also try and inculcate a habit of doing math puzzles at home. Having said that, don’t try to enforce anything on your students or children. Try and make the classes engaging and interesting. Each child is different and each of them will have their own talent and interest.

**Tricky Maths puzzles for kids will:**

Without further ado, let’s look at some tricky Maths puzzles with answers for kids.

**1.Yesterday, Today & Tomorrow!**

**I was 10 years old the day before yesterday. By next year, I will be 13 years old. How is that possible?**

This is a very interesting tricky Maths puzzle that is sure to get the kids thinking and exploring. The answer is very simple yet needs a lot of attention.

Assume that I am making this statement on January 1st, 2020 and that my Birthday is on 31st December. So, This means that my eleventh birthday was on 31st December 2019. The day before yesterday, I was 10 years old, today I am 11. By the end of the current year, 2020, I will be 12 years old. And so, by the next year (i.e. in 2021), I will be 13 years old.

Quite a tricky one isn’t it. It will be easier for the kids to crack this question if they have a calendar in hand.

**2.How old is he?**

**Mathew had 6 siblings. They were all born 2 years apart. The youngest is Izza who is only 7 years old while Mathew is the oldest. What is Mathew’s age?**

This is another trick question that will get your children thinking. This will be helpful to increase their attention and mathematical skills. Quite often children get stressed while preparing for exams. Such puzzles will help to overcome stress.

Izza, the youngest sibling is 7 years old. It is said that each sibling was born 2 years apart, and in total, there are seven children (Mathew and his 6 siblings). So Mathew’s age is:

7 + 2 + 2 + 2 + 2 + 2 + 2 = 19.

**3.Tigers and Rabbits**

**Six tigers can catch just six rabbits in six minutes. So how many tigers will be needed to catch 60 rabbits in sixty minutes?**

The immediate answer would be 60. But however, that is not the right answer. With Mathematics, there’s always something under the carpet. You have to look close.

Here,

1 tiger can catch 1 rabbit in six minutes. In 60 minutes, each tiger can catch 10 rabbits. So, each tiger can catch ten rabbits, and in sixty minutes, 6 tigers can catch 60 rabbits.

**Alternative method **– Six Tigers. How did we arrive at this? It is said in the question that 6 tigers can catch six rabbits in 6 minutes. If you multiply it by ten, the same tigers can catch sixty rabbits in 60 minutes.

**4.Wheels and the Cycles**

Last weekend, Amit went to an exhibition near his house. He rode his new bicycle gifted by his Mother for winning the Maths puzzle competition. After reaching the exhibition, Amit saw that there were 14 tricycles and bicycles in total. If there were a total of 38 wheels, how many tricycles were there in the park?

There were 10 Tricycles.

It is said that there were 14 cycles in total. We know that all of them have at least 2 wheels.

So, 14 x 2 = 28.

Now, it is said that there are 38 wheels totally, which means 38 – 28 = 10.

So, this means there are 10 cycles with one extra wheel each, that gives us the answer, 10 tricycles in total.

**5.A wizard was on the way to his house and a few drops from his magic potion fell on to a plant. Now, the plant will double its size every day. It is growing in a circular pond with a circumference of 600 meters. The plant-covered half the pond in 28 days, how many days would it take to cover the full pond?**

The answer is very simple. It would cover the full pond in 29 days. As mentioned in the beginning, the plant doubles in size every day. If it has covered half the pond in 28 days, it would grow twice that size the next day. Sometimes, the key to the answer is very simple.

**6.Magic Number**

This is a magic number. If you add this number to the number itself and then multiply by it 4 and Again divide the number by 8 and you will get the same number once more. Which is that number?

Any number will give you the same result.

For example, let’s take 2

2+2 = 4

4*4= 16

16 divided by 8= 2!

Let’s try a different number,6

6+6= 12

12 * 4= 48

48 divided by 8 = 6!

Similarly, this works for all the numbers

**7.Analyze the pattern and find the missing number:**

When you look closely, you will understand that each of the circle adds to form a total of 20. So, in the last circle:

2+9+8+?= 20
