Nikhilam Method of Complementing**

"Subtract all from nine and the last from ten“.Then getting the above complement of the subtrahend.We add the subtrahend and minuend to get the subtraction result required.

For example 1000 - 357 = ? (subtraction from 1000)

We
simply take each figure in 357 from 9 and the last figure from 10.

Step 1. 9-3 = 6

Step 2. 9-5 = 4

Step 3. 10-7 = 3

So the answer is 1000 - 357 = 643

For example 1000 - 357 = 643

We simply take each figure in 357 from 9 and the last figure from 10.

So the answer is 1000 - 357 = 643

And thats all there is to it!

This always works for subtractions from numbers consisting of a 1 followed by noughts: 100; 1000; 10,000 etc.

Similarly 10,000 - 1049 = 8951

For
1000 - 83, in which we have more zeros than figures in the numbers being
subtracted, we simply suppose 83 is 083.

So 1000 - 83 becomes 1000 - 083 = 917
