Solving (-2)x(-7)x(-5)+(-5)x(-6)

This problem involves multiplying and adding negative numbers. Let's break it down step by step.

Understanding the Rules of Multiplication with Negative Numbers

  • Even number of negative signs: If you multiply an even number of negative numbers, the result is positive.
  • Odd number of negative signs: If you multiply an odd number of negative numbers, the result is negative.

Solving the Problem

  1. Multiplication:

    • (-2)x(-7)x(-5) = -70 (Odd number of negative signs, so the product is negative)
    • (-5)x(-6) = 30 (Even number of negative signs, so the product is positive)
  2. Addition:

    • -70 + 30 = -40

Therefore, (-2)x(-7)x(-5)+(-5)x(-6) = -40
