Question

7. In which step does a mistake first occur?

Answer 1

Answer:

8+2+

Step-by-step explanation:

Answer 2

PEMDAS is an acronym for the order of operations. Parentheses, exponents, multiplication, division, addition, subtraction.

For question 7:
8 + 2 + (3 x 3 -2)
I believe the mistake is in step 1. I believe it should be:
8 + 2 + (9 -2)

We go by order of operations from left to right.

For question 8, the mistake is in step 1. They divided 24 by 3 instead of adding. It should be:
(27 + 10) - 14 + 2
