2) Gyarasguna Sutra -

3) Ekanunena Purneva Sutra -

First, subtract 1 from 11, then subtract the resulting number from 99 or 999.

4) Antyaordasake Pi.

In this method, Multiplication can be done as follows -

Example -

(1) 42 x 48

First Number = 42

Second number = 48

Add 1 to the first digit of the second number -

= 4 + 1 = 5.

Now Multiply first digits of both numbers

4 x 5 = 20 .

Now, Multiply second digits of both numbers

2 x 8 = 16.

So, 42 x 48 = 2016

(2) 54 x 56

5 x 6 = 30

4 x 6 = 24

So, 54 x 56 = 3024.

5) Navamguna Sutra -

In this method, Multiplication can be done as follows -

Example -

(1) 42 x 9

42 (10-1)

42 x 10 - 42 x 1

420 - 42 = 378.

So, 42 x 9 = 378.

(2) 72 x 99

72 (100 - 1)

72 x 100 - 72 x 1

7200 - 72 = 7128.

So, 72 x 99 = 7128
