The United States quarter has a long and interesting history. The first quarters were made way back in 1796! Over the years, the design on the quarter has changed many times. For a long time, it featured George Washington, the first president of the United States. In recent years, special quarters have been made to celebrate different states and national parks. These are called the State Quarters and America the Beautiful Quarters.

- ➖ Subtracting Quarters: If you have 75 cents and you spend one quarter, you have 75 cents - 25 cents = 50 cents left.
