Difficulty: Easy
Correct Answer: x x
Explanation:
Introduction / Context:Pick two operations to make the equality hold. Try multiplication where a large result is needed, because 48 is much larger than 4 and 3 individually.
Given Data / Assumptions:
Concept / Approach:The quickest way to 48 with 4, 3, and 4 is 4 × 3 × 4 = 12 × 4 = 48.
Step-by-Step Solution:
Choose “× ×”. Then 4 × 3 × 4 = 48.Verification / Alternative check:Any use of “+” or “−” cannot reach as high as 48 starting from these small integers.
Why Other Options Are Wrong:They evaluate to values different from 48 (e.g., 4 × 3 + 4 = 16).
