Adding Decimals
Grade 5 · Math · Decimals · Iowa, USA
Lesson Summary
Add decimal numbers by lining up the decimal points and adding column by column.
Explanation
Adding decimals is a lot like adding whole numbers. The key step is to line up the decimal points so that tenths are added to tenths and hundredths are added to hundredths. You can add zeros to the end of a number so both numbers have the same number of decimal places. Then add from right to left, carrying when needed, and bring the decimal point straight down into your answer.
