Chapter 1 : Great Book Of Integers Review
In integers, when adding both positive and negative with the same number they will cancel each other out making the answer a zero.
In Integers you can have zero pairs.
Zero pairs is when you have positive and negative number that is the same.
ex. (+9) + (9-) = 0
I prefer using standard form because its easier to answer and easy to understand.
ex. +9 + -1 = -10
If there is even number of positive the product will be POSITIVE
If there is a odd number the product will be NEGATIVE.
