Add 10 or 100
When 10 is added to a number, the digit at its tens place increases by 1.
For example: Consider the number 123. It can be written in the place value table as:
| Hundreds | Tens | Ones |
| 1 | 2 | 3 |
There are 2 tens in the number 123.
When 10 is added to 123, the digit at its tens place increases by 1.
2 + 1 = 3
So, 123 + 10 = 133.
