Question

Evaluate 5 - (4 + 2)2

Answer 1

Answer: -7

I used a calculator.

Answer 2

-7

Explanation:

We can follow PEMDAS and see that first we do 4+2 which is 6. Our equation looks like 5 - (6)2. Since multiplication comes before subtraction we multiply 6 * 2 which is 12. Now we can fit that in 5 - 12 = -7
