Questions & Answers

Question: I sometimes get confused about when to add and when to subtract in money questions. How can I tell the difference?

Answer: Great question! Look for key words in the question:

  • Addition words: "total," "altogether," "in all," "combined," "sum," "how much do you have"
  • Subtraction words: "left," "remaining," "difference," "more than," "less than," "change," "how much more"

Example of addition: "What is the total of 25¢ and 15¢?" (25¢ + 15¢ = 40¢)

Example of subtraction: "How much change from 50¢ if you spend 20¢?" (50¢ - 20¢ = 30¢)

If you're still unsure, try to picture the situation - are amounts being combined or taken away?

Question: What if a question has both addition and subtraction? How do I solve it?

Answer: These are called multi-step questions. Solve them in the order the events happen:

  1. Start with the initial amount
  2. Do the first operation (add or subtract)
  3. Take the result and do the next operation
  4. Continue until you've done all operations

Example: "You have 75¢. You spend 30¢ and then earn 25¢. How much do you have now?"

Step 1: Start with 75¢

Step 2: 75¢ - 30¢ = 45¢

Step 3: 45¢ + 25¢ = 70¢

You now have 70¢.

Work through each step one at a time!

Question: My child is having trouble with questions that involve both dollars and cents. How can I help?

Answer: The key is to convert everything to the same unit. Here's how:

  • Remember: 1 dollar = 100 cents
  • If you see dollars, convert them to cents by multiplying by 100
  • If your answer needs to be in dollars, convert cents to dollars by dividing by 100

Example: "I have $1.25 and spend 80¢. How much do I have left?"

Step 1: Convert $1.25 to cents = 125¢

Step 2: 125¢ - 80¢ = 45¢

Step 3: Answer is 45¢ or $0.45

Practice converting between dollars and cents until it becomes automatic!
