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.
