Vedic Math & 16 Sutras

**[s2]: All from 9 and the last from 10****[s3a]: Vertically and ****[s3b]: Cross-wise**

Example: 872 x 997 = Y ?

Apply [s2]: (8-9) =-1 , (7-9)= -2 , last (2-10) = -8

872 -> [**-128**]

[s2]: (9-9) = & (9-9)= & last (7-10)=-3

997 -> [**-003**]

Arrange in 2 vertical columns as:**872** -> [**-128**]

997 -> [**-003**]

[s3a]: (Vertically):

[**-128**] x [**-003**] =**384**

[s3b]: (Cross-wise):

872 + [**-003**] = **869**

=> Y = **869**,**384**

Now, Quick Demo : Calculate 892,763 x 999,998 = Y

892,763 [**-107,267**]

999,998 [**-2**]

=> Y= **892,761**,**214,534**
