### Vedic Math - Trick 1

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

### Re: Vedic Math - Trick 1

This is the vedic technique that I like for multiplication.

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
No great discovery was ever made without a bold guess.

Vedic Maths - Trick 2

Using VERTICALLY AND CROSSWISE you do not need to the multiplication tables beyond 5 X 5.

* Suppose you need 8 x 7

8 is 2 below 10 and 7 is 3 below 10.
Think of it like this:

The diagram below shows how you get it.

You subtract crosswise 8-3 or 7 - 2 to get 5,
the first figure of the answer.
And you multiply vertically: 2 x 3 to get 6,
the last figure of the answer.

That's all you do:

See how far the numbers are below 10, subtract one
number's deficiency from the other number, and
multiply the deficiencies together.
* 7 x 6 = 42

Here there is a carry: the 1 in the 12 goes over to make 3 into 4.

Here's how to use VERTICALLY AND CROSSWISE for multiplying numbers close to 100.

*
Suppose you want to multiply 88 by 98.

Not easy,you might think. But with
VERTICALLY AND CROSSWISE you can give
the answer immediately, using the same method
as above.

Both 88 and 98 are close to 100.
88 is 12 below 100 and 98 is 2 below 100.

You can imagine the sum set out like this:

As before the 86 comes from
subtracting crosswise: 88 - 2 = 86
(or 98 - 12 = 86: you can subtract
either way, you will always get
And the 24 in the answer is
just 12 x 2: you multiply vertically.
So 88 x 98 = 8624

### Re: Vedic Math - Trick 1

I was not getting the concept of this trick clearly I was confuse from the second line.

For example 1000 - 357 = 643
We simply take each figure in 357 from 9 and the last figure from 10.

If you can clarify then please clear this line so that I can understand this trick.

### Re: Vedic Math - Trick 1

What if the numbers are one, a single-digit number and the other, a double-digit. Do you use 100 for both or 10 and 100.

Only a friend tells you your face is dirty.
