MULTI-STEP WORD PROBLEMS Using Addition & Su btraction in Multi-Step Work Problems Some word problems require MORE than one step to solve. These are called multi-step word problems. When reading a word problem you should: Think about what the question is asking. Make a plan in your head or on paper for how to solve the problem. Decide whether you are going to need to add, subtract, multiply, or divide…or if you will need to use a combination of these operations. Decide the order of the steps you need to take in order to solve the problem. Let’s Practice: Frank bought a book for $5.25 and a candy bar for $0.50. He gave the cashier $10.00. How much change did he get back? First, decide what steps we need to take in order to solve the problem. Step 1: Decide what the question is asking: It is asking how much change Frank is going to receive back from the $10.00 he gave the cashier. Step 2: Next, find out how much Frank is going to spend when buying the book and the candy bar together. So that means you must ADD the costs of the book and the candy bar. $5.25 (book) + $0.50 (candy bar) $5.75 © Copyright NewPath Learning. All Rights Reserved.

Step 3: Now we know how much his items cost. Next, we need to SUBTRACT the cost of $5.75 from $10.00 in order to find how much change Frank is going to receive. $10.00 (what Frank gave the cashier) - $ 5.75 (how much Frank spent) $ 4.25 Frank will receive $4.25 change from the cashier. You Try: Sarah had 30 cookies. Her brother ate 7 cookies, her dad ate 5 cookies, and her mom ate 3 cookies. How many cookies does Sarah have now? Step 1: First, figure out how many cookies her family ate. Step 2: Next, subtract the number of cookies that were eaten from 30. That will tell you how many cookies Sarah has left. If you answered 15 cookies, then you are right! Here are the answers to the steps if you need them: Step 1: 7 + 5 + 3 = 15 cookies were eaten Step 2: 30 – 15 = 15 cookies were left © Copyright NewPath Learning. All Rights Reserved.
