Classic brain training methods are perhaps puzzles like crosswords or sudoku, but in recent times I have become more and more attracted to the type of challenge you’ll see below.

These types of puzzles have been flooding the web lately, probably because they are really fun!

These are old classic mathematical problems. When you were in middle or high school.

These tests are more fun when you find yourself trying to remember the math you learned as a child.

**Can you figure out the correct solution?**

Knowledge degrades

So now I’m going to treat you to a math problem designed for school students. But it’s not that simple for those of us who graduated decades ago. It’s easy to forget the order of operations as we grow older.

Now to the brainteaser – can you figure out the answer? Try to think back on the mathematical rules!

Here is a tricky math problem for you.

**5 x 5 / 5 (1+4)=?**

Have you gotten the answer? Or are you having a hard time solving the question?

A

B

C

**RESULT**

**Well, here’s the answer: 25!**

Are you confused about how we arrived at that? Here’s how to go about it:

Start solving from left to right, multiply 5 by 5, and you get 25. Then divide your answer by 5, and that takes you right back to 5.

Add (1+4) that equals 5, then multiply it by 5, which gives you 25! It wasn’t so hard, right? You just needed focus!

**Did you get it right without looking?**
