## What is the connection between the rules for multiplication and the rules for Division?

Adding and subtracting with negative numbers We now move on to other rules we use when working out calculations. What happens if we have calculations which involve positive and negative numbers?

How do you teach the connection between multiplication and division?

They are opposite operations, and both have to do with groups of equal size. Students write multiplication and division sentences from the same picture. In the later exercises, they write a division fact that matches the given multiplication, and vice versa. Lastly, students use their knowledge of multiplication facts to solve division problems.

How is inverse operation used in Division and multiplication?
