In math class, we recently started a new unit on Integers. Ms. Andrews expects us to be able to add, subtract, multiply, and divide integers. So far, we only started adding and subtracting them. The rule for adding is: when the integers are different you subtract the smaller number by the bigger number and keep the integer of the bigger number. If they are the same you add normally. A rule to help you with subtracting is KFC. This stands for "keep", "flip", and "change". You just change the last number and add instead. Soon, we will be starting multiplication and division.
