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.

This 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 solve this equation – without a calculator?**

Okay, now to the challenge.

Below is a tricky equation. Can you solve it without using a calculator?

What do you think the right answer is?

Did you find the correct answer?

Make sure you started from the right place – just solving straight from left to right can easily mess you up.

**Below we will present the correct answer.**

What do you think the answer is? 3 or 12?

If you used the PEMDAS rule you would have to do the question in the parentheses first, which is 8 ÷ 4, which equals 2.

Then you must shift over to the left equation and do 24 ÷ 4= 6.

**Then you have to multiply 6 x 2 which equals 12 and there is your answer!**

**Only a few people can solve it: Are you clever enough to pass this math test?**

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?**

**Here is the challenge, in the picture below.**

At the top of the picture we see the task and then four possible answers.

Which solution do you think is the correct one?

How did you come up with it?

Take your time and think about it so you can find the correct solution.

Done? Below you can check if you picked the right number!

**The correct answer**

**The correct answer is B: 12.**

Why is 12 the correct answer?

Well, if you remember from your school days, according to the order of operations, you do multiplication before addition and subtraction, so you start by solving 3 x 3, which results in 9.

Then we are left with a simpler math problem: 3 + 9 – 3 + 3

The answer is therefore 12.

Did you pick the correct number? Congratulations!
