subtrAction of LArge numbers

Subtraction of larger numbers is also same as subtraction of smaller numbers. To subtract
large numbers, we follow the following steps.

Step 1: Arrange the minuend and the subtrahend in columns.
Step 2: Start subtraction from the ones column, regroup the digits if needed, then move
to the tens column, and so on.

Step 3: Use regrouping if required.

example 1: Subtract 8736421 from 9932043.
Solution: tL L tth th H t O

– 8 7 3 6 4 2 1 Subtrahend and ‘subtrahend’ is equal to
the ‘minuend’, the answer is
1 1 9 5 6 2 2 Difference correct.

example 2: Subtract 57897325 from 78946852.

Solution: C tL L tth th H t O
