Coins and dollar bills are worth different amounts. A penny is 1¢. A nickel is 5¢. A dime is 10¢. A quarter is 25¢. A one-dollar bill is $1, which is the same as 100¢.
Jack has 3 quarters, 1 dime, and 2 pennies. Add up each coin: 25¢ + 25¢ + 25¢ + 10¢ + 1¢ + 1¢ = 87¢. Jack has 87¢ in all.
Cents use the ¢ symbol and dollars use the $ symbol. Since $1 equals 100¢, amounts under a dollar are usually written with ¢, like 75¢, and amounts of a dollar or more are usually written with $, like $1.25.
Emma pays with a one-dollar bill for a toy that costs 65¢. Since $1 is 100¢, subtract: 100¢ − 65¢ = 35¢. Emma gets 35¢ back in change.
Add coin values to find a total, and subtract the cost from what you paid to find your change.

U.S. coins review
Four coins do most of the work. A quarter is 25 cents. A dime is 10 cents. A nickel is 5 cents. A penny is 1 cent. Learn what each one looks like. The quarter is big with rough edges. The dime is tiny. The nickel is smooth and mid-size. The penny is brown. To count a pile, start with the big coins first. Add quarters, then dimes, then nickels, then pennies last. Big first keeps the adding easy.
How to Count Money: 9 Tips for Counting Coins and Bills
A big pile of coins looks hard to count. It is easy with a plan. First, sort the coins into groups. Put all the quarters in one spot. Put dimes, nickels, and pennies in their own spots. Next, count each group. Start with quarters, then dimes, then nickels. Pennies come last. Write each group total down. Add the groups. For bills, sort by kind too. Ones with ones, fives with fives. Use $ for dollars and the cent mark for coins under one dollar. 52 cents can be 52¢ or $0.52.
