A useful order

  1. Sort coins and bills from largest to smallest.
  2. Add the largest first, then keep adding.
  3. Group small coins into known amounts (e.g. four quarters = $1).

Quick fact pairs

  • 2 nickels = 1 dime (10¢)
  • 5 nickels = 1 quarter (25¢)
  • 4 quarters = 1 dollar
  • 10 dimes = 1 dollar

Making change

A pizza is $7.65. You pay with a $10. The change is $10.00 − $7.65 = $2.35. Cashiers often count up: 65¢ to make $7.65 into $7.66 wait, that's wrong — they count up from 7.65: 35¢ takes you to 8, then 2 dollars takes you to 10. So 35¢ + $2 = $2.35.
