Example Line up the decimal points __________________________ Add the columns __________________________ 1.03

Example Line up the decimal points _____________________________ Add the columns _____________________________ 9.04

To subtract decimals Line up the decimal points. Subtract the columns from right to left, regrouping if necessary. Place a decimal point in the answer directly below the other decimal points.

Example – 0.49 Line up the decimal points __________________________ Regroup the tenths. Subtract the columns __________________________
