103 • [12 ÷ (10 – 4 • 2)] + 3
PEMDAS. We need to take care of the parenthesis, first.
103 • [12 ÷ (10 – 4 • 2)] + 3
Inside the parenthesis, we must do the other parenthesis inside and follow PEMDAS in there.
103 • [12 ÷ (10 – 8)] + 3
103 • [12 ÷ (2)] + 3
103 • [12 ÷ 2] + 3
103 • [6] + 3
103 • 6 + 3
Now, we can do multiplication.
103 • 6 + 3
618 + 3
621
Your final answer is 621.
