What is a decimal?
A decimal represents parts of a whole using place value. In 2.45, the 4 is in the tenths place and the 5 is in the hundredths place. The generator covers adding tenths, adding hundredths, and subtracting dollar amounts.
How do you add decimals?
Align the decimal points
Write tenths below tenths and hundredths below hundredths.
Fill in missing places
Add a trailing zero if it makes the columns easier to follow: 1.3 is the same as 1.30.
Add and keep the decimal point
Work from right to left, carrying if needed, and put the point directly below the others.
Worked example: 2.45 + 1.30
Add hundredths: 5 + 0 = 5. Add tenths: 4 + 3 = 7. Add ones: 2 + 1 = 3. Keep the decimal point aligned. The result is 3.75.

Add tenths
Line up the decimal points before adding. For example, 1.4 + 2.3 = 3.7. The answer keeps one digit after the decimal point.
Add hundredths
Work with two decimal places, such as 2.45 + 1.20 = 3.65. The answer key shows two places, including trailing zeros.
Subtract dollar amounts
Use US dollar notation to practice money arithmetic. For example, $8.50 − $3.25 = $5.25. The first amount is always larger.
