To the rights of the decimal point are:
Tenths, hundredths, thousandths, ten thousandths, hundred thousands, and so on

Rules for decimal number addition:
- By take down the numbers, one under other decimal number, with the decimal points arranged in lined up manner and then,
- Put zeros in place where the numbers have the same length
- After that add normally and remember to put the decimal point in the answer then only answer will be in decimal.
