To subtract decimals, line up the decimal points of the numbers being subtracted and add zeros to make them the same length. Then subtract as usual and place the decimal point in the answer. This process is demonstrated through two examples, subtracting 0.03 from 1.1 to get 1.07 and subtracting 0.55 from 7.005 to get 6.455, which are equivalent to subtracting whole numbers with the decimal point in a different position.

1. Subtracting Decimals
Subtracting decimals is easy when you keep your work neat
To subtract decimals, follow these steps:
 Write down the two numbers, one under the other, with the decimal points lined
up.
 Add zeros so the numbers have the same length
 Then subtract normally, remembering to put the decimal point in the answer
Example: Subtract 0.03 from 1.1
Line the decimals up: 1.1
− 0.03
"Pad" with zeros: 1.10
− 0.03
Subtract: 1.10
− 0.03
1.07
Answer: 1.07
That was just like 110 − 3 = 107, but with the decimal point in a different
position
Example: Calculate 7.005-0.55
Line the decimals up: 7.005
− 0.55
"Pad" with zeros: 7.005
− 0.550

2. Subtract: 7.005
− 0.550
6.455
Answer: 6.455
And that was just like 7005 − 550 = 6455
