Using Math While Shopping

Shopping is a perfect time to use addition, subtraction, and place value!

  • Add up the prices of things in your cart.
  • Subtract to find out how much change you get back.
  • Use rounding to estimate totals.

Math helps you make smart choices and stick to your budget.

Examples

  • You have $10 and buy a toy for $7. How much will you have left? ($3)

  • If apples are $2 each and you buy 4, that's $8 total.
