# Dividing Integers

A question like -6 divided by -2 is asking us this:

How many lots of -2 are contained in -6 ?

We could probably work this out in our head, or else draw a diagram to help us get the answer.

The above example shows that a negative number divided by a negative number gives a positive answer.

If we do the mathematics for all possible combinations, we find that the following applies.

These dividing rules can be summarised in the following diagram.

If we go back and look at our previous lesson on Multiplying Integers, by clicking the following link:

we notice that the dividing rules for answers are exactly the same as the multiplying rules.

Dividing Integers Examples

The following examples show how to work out the four main types of Integer Dividing Questions.

The working out steps are as follows:

1) Write down the question

2) Work out which of the four Dividing Rules we need to use to get the Sign of the answer (eg. Positive or Negative answer).

3) Pretend the signs are not there, and divide the numbers as normal.

4) Combine the results from steps 2 and 3 to form the final answer.
