Multiplying and Dividing with Negatives
Multiplying with Negatives
There's a simple rule here:
- (positive) (positive) = (positive)
- (positive) (negative) = (negative)
- (negative) (positive) = (negative)
- (negative) (negative) = (positive)
Example :
Important Thing To Notice:
Since a positive times a positive is positive, and a negative times a negative is also positive, it follows that any number times itself is either zero or positive.
Dividing with Negatives
The same rule works with division:
- (positive) (positive) = (positive)
- (positive) (negative) = (negative)
- (negative) (positive) = (negative)
- (negative) (negative) = (positive)
