DETERMINE THE ONE OPERATION FUNCTION What Is a One Operation Function? A one operation function is an equation with only one of the following operations: addition, subtraction, multiplication, or division. How to determine the one operation function: When given a story problem where you need to determine the operation, be sure to look for clues. Here are a few examples of clues you may find: Addition Subtraction Multiplication Division more, together have left, have now together each, equally, shared These clues will help you figure out which operation to use to solve the problem. For example: Maggie and Derek are going to share equally a bag of jelly beans. The bag has 32 pieces in it. How many jelly beans will each of them get? The problem mentions share, each, and equally. So we know that Maggie and Derek are going to divide the bag up evenly between them. There are 32 pieces they will be sharing and there are two of them that are sharing. In order to solve this problem, you would divide 32 by 2. 32 ÷ 2 = 16 Maggie and Derek will each receive 16 jelly beans. © Copyright NewPath Learning. All Rights Reserved.
