Add the following 5 numbers:
2 + 4 + 6 + 8 + 10
Add up the entries in blue for Column 2
| 1 | 0 | |
| 8 | ||
| 6 | ||
| 4 | ||
| + | 2 | |
| 0 |
Column 2 → 0 + 8 + 6 + 4 + 2 = 20
Since 20 is greater than 9, we take the digit farthest to the right of our answer which is 0
We also carry the digit farthest to the left which is 2 for Column 1
Add up the entries in blue for Column 1
| 2 | ||
| 1 | 0 | |
| 8 | ||
| 6 | ||
| 4 | ||
| + | 2 | |
| 3 | 0 |
We carry a value of 2 from the last step
Column 1 → 2 + 1 = 3
Final Answer
30
