SubtraCtion of largE nuMbErS

Subtraction of larger numbers is the same as subtraction of smaller numbers. To subtract

large numbers, we follow the steps.
Step 1: Arrange the minuend and the subtrahend in columns.

Step 2: Start subtraction from the ones column, then move to the tens column, and so on.
Step 3: Use regrouping if required.

example 1: Subtract 87,36,421 from 99,32,043.
