Change Calculator

Not everybody can calculate correct change in their head. Not everyone has a cash register handy. But you still need to figure correct change when somebody gives you money for something.

This app does that--enter the price, then enter how many 20s, 10s, 5s, 1s, quarters, dimes, nickels and pennies your customer gives you. The calculator tells you how many you need to give back.

In addition, there's a practice mode. In "Settings" pick a difficulty level L1 (easiest) to L8 (hardest) you're comfortable with. Practice until you're really fast. Then go to the next level. When you're fast and accurate at L8, you're able to calculate correct change in your head for any situation. Then you won't need this app! But you'll have it just in case.
