Identify the expression which represents the calculation "add 8 and 7, then multiply by 2."

Question

A) (2 x 8) + 7
B) 8 + (7 x 2)
C) 2 + (8 x 7)
D) 2 x (8 + 7)

Answer 1

so, which choice does the addition first? Think PEMDAS

Answer 2

8+(7x2)

Answer 3

Actually, the problem says "add 8 and 7, then multiply by 2", so we should add 8 and 7 first, and only then multiply by 2. So the correct expression is:

(8 + 7) x 2

which simplifies to:

15 x 2

and the final answer is:

30
