How Many Of These Easy Yet Brain-Twist Math Problems Can You Solve?

Some were born with a gifted ability in Math while others struggle with the subject from first grade till high school and even higher education.

And the following math problems went viral as they are far more complicated than they sound, twisting many people’s brains. Check out our list and see how many of them have you seen or solved.

1. This math problem has two right answers

This question was created by Go Tumble, shared on Wiki, and went viral on Facebook.

It can be solved in two ways. The first one is adding the equation, combine the sum with the sum of the previous equation. The second way is to multiply the second number of this equation by the one you’re adding to it.

The solutions will result in 40 or 96.

2. This problem got more than 5 million views on YouTube

To solve this problem correctly, you need to rely on the modern interpretation of BODMAS or PEMDAS, aka the order of operations: Brackets > Orders/Exponents > Division/Multiplication > Subtraction/Addition. In the case of precedence, we go from left to right.

The right answer to this problem is 9. But people are controversial in the right way to solve this problem due to a 1917 order of operations, which is a bit different. This old version will result in 1.

3. This math quiz, on the other hand, took Reddit by storm

In the first question, the student is asked to use repeated addition to calculate 5x3. The student answered was “5 + 5 + 5,” the teacher marked it as wrong and wrote down the correct answer as “3 + 3 + 3 + 3 + 3.”

In the second question, the student had to use an array to calculate 4 x 6. The student drew six arrows, four columns and was marked wrong again. The correct answer that the teacher wrote was four rows, six columns.

4. A math problem comes from Singapore to the US to mess with heads

A man in Singapore went on Facebook and shared a picture of a 5th-grade math question, which got almost 6,000 shares.

The logic puzzle said that Cheryl gives Bernard and Albert different information about her birthday and the friends had to figure out the date from a list of options. She tells the month to Bernard while telling the day to Albert.

The answer to this problem is July 16, which you can find out through a table of dates and by using the elimination process.

5. This math question is for 2nd grade but even parents got confused

In a now-deleted tweet, a mother shared a math problem that was picked up by the Parents Against Primary Testing Facebook page as well as media outlets.

The problem, in fact, was rather simple. Say, 19 people that got off the train is represented by -19 while 17 got on is represented by +17.

The net loss is: -19 + 17 = +2. Since 63 people are now on the train, the initial number of people on the train is: 63 + 2 = 65.

The controversy occurred as many believed the correct answer must be 46.

6. A math question that doesn’t involve math

This problem has a simple way to solve: you just need to turn the image upside down, from which you will notice that the numbers are in ascending order from 86 to 91.

That means the correct answer is 87.

7. It’s a trick question

In fact, nothing is missing, it just deliberately confuses readers through wording. If you focus on the total instead of the debt, it all adds up.

8. A math problem from Vietnam, which isn't difficult but rather time-consuming

The challenge here is to fill in the blank square with numbers from 1 to 9 and each number can be used only once so that the equation results in 66.

VNExpress said that this puzzle is designed for 3rd grade. You don’t have to use any complicated math or tricks to solve this problem but it instead takes trial and error as well as the process of elimination.

9. Over half the students at Princeton, MIT, and Havard got the wrong answer to this question

It may take less than a second for one to say that the answer is $0.1, but that’s a wrong answer. If the ball costs $0.1 dollar, that makes the bat cost $1.0 and the bat will be only $0.9 more than the ball.

The correct answer here is $0.05. That means the bat costs $1.05: $1.05 - $0.05 = $1.0.

10. Only 1 out of 10 people can finish this calculation without using a calculator

The easiest way to calculate this without a calculator is to round the numbers down or up to multiples of five, then estimate the result and choose an option that’s closest to your estimated answer.
