Answer:
He should have divided 12 ÷ 3 first.
Step-by-step explanation:
Following PEMDAS/BODMAS, the first step is solving equations in parentheses. Since the parentheses contain a multi-step equation, Jay needs to follow PEMDAS for inside the parentheses as well. Instead of adding 3+12 first, he should have done division first (12 ÷ 3).
How the problem should be solved:
-3 × (3 + 12 ÷ 3) - 4
-3 × (3 + 4) -4
-3 × 7 - 4
-21 - 4
-25
