A penny is worth 1 cent, a dime is worth 10 cents and a dollar is worth 100 cents.

How to add dollars, dimes and pennies.

• Count by hundreds the number of dollars to find the number of cents the dollars are worth
• Starting at this total, count up by tens for the number of dimes.
• Count the number of pennies by ones starting at the previous total.

Example: How many cents are 7 dollars, 4 dimes and 3 pennies worth?

• Count by hundreds seven times for the seven dollars 100, 200, 300, 400, 500, 600, 700
• Count by tens for the 4 dimes: 710, 720, 730, 740
• Count by ones for the 3 pennies: 741, 742, 743
• Answer: 7 dollars, 4 dimes and 3 pennies are worth 743¢
• 743¢ is the same as $7.43 since there are 100 cents per dollar
