Today’s task looks simple at first glance, but it will quickly test your attention and your ability to follow the correct order of operations. With just a moment’s inattention, the result can go in a completely different direction.

Tune in for a short mental workout before you tackle the example itself. Many people find tasks like this unexpectedly challenging, even if they look innocent on paper. They can sometimes frustrate even those who feel at home among the numbers, and that’s where their charm lies.

What test to take

In the picture you see the following example: 12 : 3 (2 + 2). Your job is to choose the correct order of steps and think carefully about what to do first. Parentheses, division and multiplication all play a role here and it’s up to you how quickly you can reach the final result.

And how did you do?

Did you manage to find the right number? The result is 16.

First we calculate the parenthesis: 2 + 2 = 4. Then we solve the expression 12 : 3, which is 4. Finally, 4 × 4 = 16.
