Subtract 10 or 100

When 100 is subtracted from a number, the digit at its hundreds place decreases by 1.

 

For example: Consider the number 567. It can be written in the place value table as:

 

Hundreds	Tens	Ones
5	6	7

 

There are 5 hundreds in the number 567.

 

When 100 is subtracted from 567, the digit at its hundreds place decreases by 1.

 

5 – 1 = 4

 

So, 567 – 100 = 467.
