Technical Math For Dummies

Although many cashiers simply dump all your change in your hand at once, counting change the old-fashioned way ensures that customers get the proper amount. Here’s an easy way to make a customer’s change, using counting and simple addition:

1. Leave the payment in plain sight on top of the cash drawer.

Say your customer gives you a \$10.00 bill for a \$9.56 purchase. Put it on the cash drawer while you gather the change.

2. Count the change out and give it back to the customer, starting with the smallest coins and describing what you’re giving.

For the example of \$9.56, say

“Your purchase was \$9.56, out of \$10.00. That’s \$9.56,

plus 4 cents (4 pennies) makes \$9.60,

plus 5 cents (a nickel) makes \$9.65,

plus 10 cents (a dime) makes \$9.75,

plus 25 cents (a quarter) makes \$10.00.”
