 Decimals Addition Adding decimals To add decimals, follow these steps: Write down the numbers, one under the other, with the decimal points lined up. Add zeros so the numbers have the same length Then add normally, remembering to put the decimal point in the answer Add 5.3 to 7.04 Line the decimals up, "pad" with zeros and add: Add the following decimals: $\;2.2\;+\;1.9\;+\;2.3\;=$
