Difficulty: Easy
Correct Answer: + - =
Explanation:
Introduction / Context:You must select the correct pair of operations and the equality sign so that the numerical statement becomes a true equation. Standard operator precedence applies on the left side before comparing to the right side of “=” if present.
Given Data / Assumptions:
Concept / Approach:Look for combinations that can naturally form 32, since 24 is near 32. The simplest attempt is to place “=” as the last operator so the entire left expression reduces to 32.
Step-by-Step Solution:
Try Option D: 24 + 16 − 8 = 32.Evaluate LHS: 24 + 16 = 40; 40 − 8 = 32.Hence 32 = 32, which is true.Verification / Alternative check:Quickly test other options:
Why Other Options Are Wrong:They evaluate to non-32 values on the left, so the equality fails.
