Find the sign of the following multiplication sentence.

(−a) × (−b) × (−c)


Answer:


Step by Step Explanation:
  1. On observing the question carefully, we find that there are three negative integers in the given expression.
  2. Solving:

    (−a) × (−b) × (−c) = ((−a) × (−b)) × (−c)   [As (−) × (−) = (+)]

    = (ab) × (−c)   [As (+) × (−) = (−)]

    = −abc

  3. So, the sign of (−a) × (−b) × (−c) is negative (−).
