# Very few people can solve this math problem without using a calculator

We all know how important it is to exercise regularly if you want to live a long and happy life. But what most people forget is that it is just as important to do the same for your brain, especially when you start getting a little older.

There are, of course, many ways to exercise the brain, crosswords and sudoku, for example, used to be the most popular back in the day. Lately, however, a whole new kind of challenge has emerged, causing waves of frustration and upsets online!

Doing a little brainteaser is never a bad thing, your mind becomes clearer after challenging itself a little. And not in the way you challenge it during work. There is no pressure, only satisfaction in these kinds of exercises.

The challenge below is one of my favorites!

## Trying to remember school math

## Solve the problem – without a calculator

Okay, to the challenge. Below we see a picture with a math problem. Can you solve it without a calculator – what answer will you come up with?

How was it? Take your time and concentrate! Below you will see the correct answer.

## Here is the solution

The answer is **104.**

Why is **104** the correct answer? You might ask.

For starters, we have to calculate the multiplication, **25 x 0**, which becomes **0**.

Then we have the number **50 + 50 – 0 + 2 + 2 ** which is **104**.

So again, the answer is **104**.
