**Solve the problem without a calculator**

The task below is a classic math problem from primary school. It is important to remember the order of operations if you want to get the right result, which is not easy after all these years.

Below we can see the challenge. Can you solve it?

**5 + 7 (2 + 1) = ?**

What could the answer be?

Look closely and think, how were you supposed to solve equations with parenthesis?

The correct answer is below.

A

B

C

**Math challenge’s solution**

Let us see if you are as sharp in math as to when you were little and went to school. The solution will be under the next picture.

**The correct answer is 26.**

How did we get 26?

According to the order of operations, first, you solve the equation inside the parentheses, 2 + 1, which becomes 3.

Then we multiply 7 by 3, which totals in 21.

What remains is 5 + 21 = 26.

**Did you get it right? Good work!**
