Vedic maths for kids...

Use the formula ALL FROM 9 AND THE LAST FROM 10 to
perform instant subtractions.
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
