UNIT 14: DECIMAL SUBTRACTION

Decimal subtraction is similar to decimal addition. You write down both decimals one above the other with their decimal points lined up. Then you just substract as you would 2 whole numbers, with borrows if necessary.

EXAMPLES:




Subtract these decimals: (Allow me to line up the first one!)

1) 2.3 - 1.1 =
2) 44.2 - .2



3) 9.31 - 1.2
4) 6.66 - 4.48



5) 16.23 - 1.4 6) 1.06 - .1



7) 144.2 - 128.3 8) 29 - 1.4



9) 14.4 - 13.9 10) 18.1 - 1.44



11) 32.6 - 2.88 12) This problem is hard!
