When dividing real numbers, the quotient will be positive if the signs are the same and it will be negative if the signs are different.

- 9

Practice makes perfect
When dividing real numbers, the quotient will be positive if the signs are the same and it will be negative if the signs are different. cc Same Sign & Different Signs (+)(+)=(+) & (+)(-)=(-) (-)(-)=(+) & (-)(+)=(-)

In our case one number is positive and one number is negative, so the quotient will be negative. 18 Ă· ( - 2) = - 9 We can verify this using a calculator.
