Money in math is the way we use numbers to show the value of coins and bills. We use the dollar sign ($) for dollars and the cent sign (¢) for cents.
Remember that 100 cents always equals 1 dollar. Coins show part of a dollar, and bills show whole dollars.
Each coin has a special name and value. Knowing coin values helps you add, subtract, and make change correctly.
Think of each coin as a part of a dollar. For example, 4 quarters = $1.00, and 10 dimes = $1.00.
Bills represent dollars. You can use them alone or with coins to show amounts of money.
Bills are worth more than coins. Always count dollars first, then add coins for the total.
We add or subtract money the same way we add or subtract numbers, but we always include the dollar sign ($) or cent sign (¢).
Always line up the decimal points when adding or subtracting dollars and cents.
Word problems with money ask you to use coins and bills to find a total, compare costs, or find the change after buying something.
Read carefully to decide if you need to add, subtract, or compare. Always check that your answer makes sense with the question.
