**If we want our bodies to last for a long time, a good diet and regular exercise are a must, we all know that.**

**However, most people forget that it is just as important to keep the brain in shape, especially when you start getting a little older.**

**Of course, there are lots of different ways to keep the mind active. But one of the most traditional ones is solving brainteasers such as Crossword puzzles or Sudoku.**

**Lately, however, a whole new kind of challenge has emerged online, and apparently, it really puts those brain cells to work!**

Even if you challenge the brain at work or school, a little logical thinking with no strings attached will help you relax, so you can recharge your batteries and don’t get burned out from stress and responsibilities.

The challenge below is a great way to start if you want!

## What was the correct way?

Recently, challenges like the one below have been getting pretty popular on social media.

It’s nothing to do with impossible calculations or complex equations. It’s just honest, old-school math.

That’s probably why it’s so fun to take on these tests. Since we are trying to remember, it becomes a kind of nostalgia trip while you get to challenge your own competitiveness.

## Solve this number equation without a calculator

Okay, to the challenge itself.

Below we see a picture with a number equation.

Can you solve it without using a calculator?

Ready to exercise that brain of yours?

Do you remember the order of operations?

Think really hard, so maybe it comes back to you!

## Here is the answer

Below the picture below, you’ll find the correct answer.

The correct answer is **104.**

How did we get to **104,** you ask?

Well first, we have to calculate the multiplication, **25 x 0,** which of course becomes **0**.

Then we are left with:

**50 + 50 – 0 + 2 + 2 ** which totals **104**.

The answer is thus **104**.

**Did you get the correct answer? Congratulations in that case!**
