Find the sign of the following multiplication sentence.
(−a) × (−b) × (−c)
Answer:
−
- On observing the question carefully, we find that there are three negative integers in the given expression.
- Solving:
(−a) × (−b) × (−c) = ((−a) × (−b)) × (−c) [As (−) × (−) = (+)]
= (ab) × (−c) [As (+) × (−) = (−)]
= −abc
- So, the sign of (−a) × (−b) × (−c) is negative (−).
