Choose signs so that the equation holds true. 24 * 16 * 8 * 32

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:

  • Template: 24 {s1} 16 {s2} 8 {s3} 32
  • Exactly one of {s1..s3} is “=”.


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:

  • “÷ − =”: 24 ÷ 16 − 8 becomes a small number, not 32.
  • “− + =”: 24 − 16 + 8 = 16 ≠ 32.
  • “× ÷ =”: 24 × 16 ÷ 8 = 48 ≠ 32.


Why Other Options Are Wrong:
They evaluate to non-32 values on the left, so the equality fails.


Common Pitfalls:

  • Ignoring that the entire LHS must reduce to exactly 32 once operators are fixed.


Final Answer:
+ - =
