Multiplication and Division

There are a few basic rules to remember when multiplying and dividing positive and negative numbers. Take a look at the video (below) in which Dee Greig-Dunn, Lecturer in Mathematics and Meteorology at Solent University, explains these foundation skills and the basic rules you need to remember.

How to multiply and divide positive and negative numbers.

Rule 1

When both numbers are the same (two positive or two negative numbers) the answer will always be positive.

Rule 2

When both numbers are different (one positive number and one negative number), the answer will always be negative.

Remember: these rules apply when dividing numbers as well.
