Adding Decimals
Adding decimals is easy if you keep your work neat
To add decimals, follow these steps:
- Write down the numbers, one under the other, with the decimal points lined up.
- Add zeros so the numbers have the same length
- Then add normally, remembering to put the decimal point in the answer
Example: Add 1.452 to 1.3
| Line the decimals up: |
|
|
1.452 |
| |
|
+ |
1.3 |
| |
|
|
|
| "Pad" with zeros: |
|
|
1.452 |
| |
|
+ |
1.300 |
| |
|
|
|
| Add: |
|
|
1.452 |
| |
|
+ |
1.300 |
|
|
|
|
| |
|
|
2.752 |
Example: Add 3.25, 0.075 and 5
| Line the decimals up: |
|
|
3.25 |
| |
|
|
0.075 |
| |
|
+ |
5. |
| |
|
|
|
| "Pad" with zeros: |
|
|
3.250 |
| |
|
|
0.075 |
| |
|
+ |
5.000 |
| |
|
|
|
| Add: |
|
|
3.250 |
| |
|
|
0.075 |
| |
|
+ |
5.000 |
|
|
|
|
| |
|
|
8.325 |
That's all there is to it - just remember to line up the decimals, then add normally.
