Question

Write any three rules of vedic maths with 2 examples each.

Answer 1

1) Nikhilam Sutra

With this technique it is simpler to multiply numbers which are close to power of 10.

For example,

(i) 9*8

10-9=1

10-8=2

1*2=2

9-2=7 and 8-1=7

So, answer is: 72

(ii) 9*6

10-9=1

10-6=4

1*4=4

9-4=5

6-1=5

So, our answer is:- 54

(iii)94*96

100-94=6 and 100-96=4

6*4=24

And 94-4=90 and 96-6=90

So, our final answer is: 9024

(iv)99*96

100-99=1 and 100-96=4

1*4=04

And 99-4=95 and 96-1=95

So, our final answer is: 9504

(v) 91*95

100-91=9 and 100-95=5

9*5=45

And 91-5=86 and 95-9=86

So, our final answer is: 8645

2) Ekayunena Purvena

It is applicable whenever the multiplier completely consists of nine.

In this first coloumn is 1 less multiplicand and second coloumn is complement of above coloumn.

For example,

2*9=1 | 8

3*9=2 | 7

4*9=3 | 6

5*9=4 | 5

6*9=5 | 4

7*9=6 | 3

3) Antyaordasake'pi

Steps:-

Check if addition if last digits is 10.

If yes, multiply them and write it in 2 compartments.

For Example,

(i) 34*36

3*4 | 4*6

12| 24

1224

(ii) 83*87

8*9 |3*7

72|21

7221

(iii) 112*118

11*12|2*8

132|8

1328

(iv) 12*13

15|3*2

156

(v) 14*16

2|24

224
