Question

INSERT PARENTHESES in

Answer 1

First, let's see what the answer is when we follow this equation using PEMDAS.

5 + 4 x 2 + 6 - 2 x 2 - 1

5 + 8 + 6 - 4 - 1

14

Now, let's trying grouping 5 + 4 together, and solving it again.

(5 + 4) x 2 + 6 - 2 x 2 - 1

9 x 2 + 6 - 2 x 2 - 1

18 + 6 - 4 - 1

24 - 5

19

So, the parentheses go around 5 + 4 to get your answer!
