Show answer & explanation
Correct answer: D
Solution: Use + then − between the numbers to get 32.
24 + 16 − 8 = 32
Step 1: Add 24 and 16 to get 40.
Step 2: Subtract 8 from 40 to get 32.
Why the other operator groups fail:
Using ÷ then −: 24 ÷ 16 − 8 = 1.5 − 8 = -6.5 (not 32).
Using − then +: 24 − 16 + 8 = 8 + 8 = 16 (not 32).
Using × then ÷: 24 × 16 ÷ 8 = 384 ÷ 8 = 48 (not 32).
