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 find the correct number?**

Okay, here comes the challenge.

Which of the answers do you think is right?

Yes, just too many numbers and you might not even sure where to start. So, let’s see how you can actually solve this tricky math problem.

To arrive at the correct answer, the trick is you honestly just need to use the right order of solving operations—PEMDAS. That is an acronym for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction—and that’s the order that you need to follow.

A

B

C

**ANSWER**

For the math problem given, what you need to do is to solve the operation in the parentheses first.

18 ÷ 3 x (12 – 4) = ?

12 – 4 = 8.

That will give us 18 ÷ 3 x 8 =?

First, 18 ÷ 3 = 6.

Then, 6 x 8 gives us 48.

**Hence, the final answer is 48!**

**Make sure to follow this solving operation and get it right, every time!**
