Since the beginning of time, people have always loved a good brain teaser. We grew up reading Where’s Waldo? books and putting together puzzles. Though highly frustrating at times, we just can’t seem to resist a good riddle, challenging crossword, or game of Sudoku.

### The challenge below is one of my favorites!

It isn’t about some kind of impossible calculation, but about honest old school math. This is probably why it is so fun to take on these types of challenges, just trying to remember the process brings in a little nostalgia while giving you a sense of accomplishment at the same time.

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**.
