Add the following 3 numbers:
13562 + 258 + 99965
Add up the entries in blue for Column 6
| 9 | 9 | 9 | 6 | 5 | |
| 1 | 3 | 5 | 6 | 2 | |
| + | 2 | 5 | 8 | ||
| 5 |
Column 6 → 5 + 2 + 8 = 15
Since 15 is greater than 9, we take the digit farthest to the right of our answer which is 5
We also carry the digit farthest to the left which is 1 for Column 5
Add up the entries in blue for Column 5

| 9 | 9 | 9 | 6 | 5 | |
| 1 | 3 | 5 | 6 | 2 | |
| + | 2 | 5 | 8 | ||
| 8 | 5 |
We carry a value of 1 from the last step
Column 5 → 1 + 6 + 6 + 5 = 18
Since 18 is greater than 9, we take the digit farthest to the right of our answer which is 8
We also carry the digit farthest to the left which is 1 for Column 4
Add up the entries in blue for Column 4

| 9 | 9 | 9 | 6 | 5 | |
| 1 | 3 | 5 | 6 | 2 | |
| + | 2 | 5 | 8 | ||
| 7 | 8 | 5 |
We carry a value of 1 from the last step
Column 4 → 1 + 9 + 5 + 2 = 17
Since 17 is greater than 9, we take the digit farthest to the right of our answer which is 7
We also carry the digit farthest to the left which is 1 for Column 3
Add up the entries in blue for Column 3
| 1 | 1 | 1 | |||
| 9 | 9 | 9 | 6 | 5 | |
| 1 | 3 | 5 | 6 | 2 | |
| + | 2 | 5 | 8 | ||
| 3 | 7 | 8 | 5 |
We carry a value of 1 from the last step
Column 3 → 1 + 9 + 3 = 13
Since 13 is greater than 9, we take the digit farthest to the right of our answer which is 3
We also carry the digit farthest to the left which is 1 for Column 2
Add up the entries in blue for Column 2
| 1 | 1 | 1 | 1 | ||
| 9 | 9 | 9 | 6 | 5 | |
| 1 | 3 | 5 | 6 | 2 | |
| + | 2 | 5 | 8 | ||
| 1 | 3 | 7 | 8 | 5 |
We carry a value of 1 from the last step
Column 2 → 1 + 9 + 1 = 11
Since 11 is greater than 9, we take the digit farthest to the right of our answer which is 1
We also carry the digit farthest to the left which is 1 for Column 1
Add up the entries in blue for Column 1
| 1 | 1 | 1 | 1 | 1 | |
| 9 | 9 | 9 | 6 | 5 | |
| 1 | 3 | 5 | 6 | 2 | |
| + | 2 | 5 | 8 | ||
| 1 | 1 | 3 | 7 | 8 | 5 |
We carry a value of 1 from the last step
Column 1 → Bring down the 1 from Column 1 and we are finished
