Surely sometimes you want to go back to the time when you went to primary school and your only problems were hanging out with your friends and taking exams on Fridays. But as simple as that period of life may seem to you, you must admit that some of the math problems really knew how to cause you problems.

How are you doing with math? How do you do with math logic tasks? This math equation is intended for elementary school students and has become overnight a real Internet sensation. It was confusing to thousands people. It confuses even the best mathematicians. At first, it became popular in Japan, and now it is known all over the world. Surprising is the fact that most people can not solve it, even though it is intended for children. Try it yourself!

Most people use the wrong method to solve this task. There are two pitfalls to this problem: the sequence of operations and the awkward fractions. Well, will you be able to reach the right solution?

There is one rule to follow in solving this task, and that is the sequence of operations. Multiplication and division take precedence over addition and subtraction.

Did you solve the equation like this?

+ 1 =

= 9 – 3 / 1 / 3 + 1 =

= 9 – 3 / 3 + 1 =

= 9 – 1 + 1 =

= 9

This solution is not correct. Why? Because the order of operations is not observed. As we have said, multiplication and division take precedence over addition and subtraction.

What is the correct answer? How should this equation be solved correctly?

The equation should be set as follows:

+ 1 =

= 9 – 3 ÷ () + 1 =

= 9 – 3 x 3 + 1 =

= 9 – 9 + 1 =

= 1

Dividing characters and fractions are actually the same operations. Therefore, we can consider it as 3/1/3. We all know how fractions are divided: We change the places of the numerator and the denominator. Well, so we get: 3 × 3 / 1. It is equal to 9. Hence 9 – 9 + 1 = 1.

Congratulations! You got the right solution. The correct answer is 1.

There is another way to solve the fraction: 1/3 = 0.3333333. When we divide 3 by 0.3333333, we get 9. 3 divided by 1/3 is equal to 9. The rest is easy to solve.
