00:00:17
and India is one of the oldest civilizations in the world.
00:00:21
It has contributed to the world
00:00:23
concepts such as yoga,
00:00:26
spicy chicken tikka,
00:00:32
Vedic math is one of the world's easiest
00:00:35
and simplest way to do math.
00:00:37
We are going to combine together
00:00:38
and do some number crunching today.
00:00:41
So what we are going to first do is multiply by 11.
00:00:44
We're going to do it together,
00:00:46
so if you blink, you're going to miss it.
00:00:48
So just watch it, OK.
00:00:51
So we're going to do 32 times 11, OK.
00:00:54
So we split 3, and we split 2,
00:00:57
and we add 3 and 2 and paste it on top,
00:00:59
and we get the answer as 352.
00:01:11
Let's try another sum.
00:01:16
Exactly, that's 495.
00:01:20
And 75 times 11.
00:01:25
So it gives you 7,125,
00:01:28
1 gets carried over and it becomes 825.
00:01:35
That's how simple it is.
00:01:38
OK, this is the principle behind it
00:01:41
where a is the coefficient.
00:01:50
OK, now what we're going to do is the base method.
00:01:54
OK, this is used to multiply numbers
00:01:57
very close to the powers of 10,
00:01:59
like 10, 100, 1,000, and so on.
00:02:02
So we have a sum here, say 99 times 97.
00:02:06
OK, now tell me, is 99 more than 100 or less than 100?
00:02:12
Less by how much?
00:02:14
So we write minus 01.
00:02:18
And 97 is less than 100 by how much?
00:02:22
So we write minus 03.
00:02:23
So what we're going to do is
00:02:25
we're going to cross subtract
00:02:27
and get the first part of the answer, like this.
00:02:31
We're going to do cross subtraction.
00:02:32
97 minus 01 would give us
00:02:37
and we multiply 03 times 01 vertically,
00:02:42
and we get an answer of 03.
