Math Problem Statement

Simplify the following: -5| -4| - 3(-2) + 2

Solution

Let's analyze the given expression step by step:

Expression:
543(2)+2-5| -4| - 3(-2) + 2

  1. Evaluating the absolute value:
    Since 4=4|-4| = 4, we have: 543(2)+2-5 \cdot 4 - 3(-2) + 2

  2. Multiplying 5-5 and 44:
    203(2)+2-20 - 3(-2) + 2

  3. Multiplying 3-3 and 2-2:
    20+6+2-20 + 6 + 2

  4. Adding 20-20, 66, and 22:
    20+6=14-20 + 6 = -14
    14+2=12-14 + 2 = -12

The correct answer is 12-12, not 24-24.
