Chapter 3: Dividing Integers

Partitive Division- one where you know the total number of groups, and you are trying to find the number of items in each group

Quotative Division- one where you know the number of items in each group and are trying to find the number of groups
Sign Rule for Division- if the quotient of 2 integers with the same sign with an even amount of (-) signs then it equals positive, if the quotient of 2 integers with different signs then it equals negative.
