We do not like subtraction. How do we change an expression from using subtraction to using addition? (Hint: Think about the integer mat)
You "flip" the pieces to the same playing field.
You could also say "subtracting a number is the same as adding the additive inverse."

Clearly define what a zero pair is in relation to the integer mat.
Same shape, different color.
AKA, the shapes are additive inverses
