Subtracting Decimals
Subtracting decimals is easy if 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 |
So, 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 | ||
| Subtract: | 7.005 | ||
| - | 0.550 | ||
| 6.455 |
And that was just like 7,005 - 550 = 6,455
