Practice Adding and Subtracting Decimals in Math

Use these practice problems to test your method after reviewing the concept explanation and worked examples.

Quick Recap

Adding and subtracting numbers with decimal points by aligning the decimal points vertically so that digits with the same place value line up.

Think of money: \3.75 + \2.50. You line up the dollars with dollars, the dimes with dimes, and the pennies with pennies. The decimal point is the anchor that keeps everything in the right place.
