UNIT 12: DECIMAL ADDITION

To add decimals, you must write one above the other with their decimal points lined up, like this: Where one decimal doesn't have digits that the other one does, you put in zeroes, like this: Now, its easy! You just add the two numbers as you would two whole numbers, with carries if necessary, but you keep track of where the decimal point goes and put it in the result right under the decimal points in the two numbers being added, like this : |

Add these decimals: (I will line up the first decimal for you!)

1) | 2) | 4.4 + 8.8 |

3) | 9.09 + .2 |
4) | 16. + 1.05 |

5) | .3 + 1.55 | 6) | This problem is hard! 9.99 + 100.99 |
