Adding Integers

A Quick Review

media

2

Integers are ...

positive and negative whole numbers

{...-3, -2, -1, 0, 1, 2, 3, ...}

3

The Integers can be visualized with the number line.

As you move to the left, the numbers get smaller.

As you move right, the numbers get bigger

media

4

A useful way to think of it:

Negative numbers are to the left, so minus means "go left".

Positive numbers are to the right, so plus means "go right".
