Okay, now onto the challenge itself.

In the picture below, we see a mathematics problem made for middle schoolers.

Think about it carefully so you answer correctly!

Below the next picture, you will find the correct answer.

A

B

C

Here’s the answer.

The correct answer is 11.

How do we know that 11 is the right answer?

To begin with, we need to solve the part inside the parenthesis, 12 ÷ 4 + 1, which equals 4.

After that, the problem looks like this: 15 – 1 x 4. So the next step is to calculate the multiplication, which equals 4.

So the problem now is 15 – 4, which totals 11.

The answer is then 11.

Did you get it right? Congratulations!
