Hi all,
Previously i asked a questn for multiplying BIG nos (eg. 95*95, 65*65, 75*75,etc). One answerer gave a way for it.
""""
for squares of 5 (15*15, 25*25, 35*35) follow this rule
first digit * (1+first digit) then put the 25 after it.
15*15 = 1*2=2 ->225
35*35 = 3*4 = 12 ->1225
650*650 = 6*7 = 42 ->422,500
"""""""""
I thank her. Now apart from squares of 5, what are the ways for multiplying BIG nos. QUICKLY (for eg. 68*69, 76*99, 366*98, 1658*463,1532*2351, etc........................)
Pl give me a way for multiplying large nos quickly.
Thanks........
