The trick is derived from NIKHILAM SUTRA of Vedic Math.
Multiplication it will be hard to multiply complex problems and it is a time-taking process. For these complex problems, in our Vedas we have a beautiful trick. This will formula will solve your complex formulas.
XN1*XN2=X(X+1)/N1*N2
Here left digits are same but right digits are different. For these base is not used. It is easily understand by examples
Example1:
96*94=9(9+1)/6*4
=9(10)/24
=90/24=9024
Example2:
114*116=11(11+1)/4*6
=11(12)/24
=132/24=13224
Example3:
191*109=1(1+1)/91*09
=1(2)/819 (here n1 and n2 are two digits numbers so we add zero at left side)
=20/819=20819
don’t miss.
Multiplication trick you never seen in school/college part 1.
