2.2 - Adding Integers with Tiles

Brackets:

We use brackets to make sure we don't get confused between symbols for positive and negative integers and between operations that tell us to add or subtract these integers.

-3 + -4 or (-3) + (-4)

In order to add integers with tiles, follow these steps:
1.) Draw positive and negative tiles to represent each integer in the equation.
2.) Put the zero pairs together – these tiles cancel each other out.
3.) Count the remaining positive or negative tiles that remain.
4.) The integer represented by these tiles is your answer.
