How to multiply 2 digit number in short in less than 1sec

Sonali A.

20/04/2017 0 1

27*39

First multiply 7*9=63 write '3' and take 6 as carry.

Then cross multiplication i.e. multiply '7*3'=21 and '9*2'=18 add '21+18+6(carry from first multiplication)' = 45. write 5 out of 45 on the left of 3 and carry 4.

Then multiply '3*2'=6 add'6+4(carry from last addition)'= 10.

So your answer is 27*39 = 1053.

If you practise for 5-7 times the process can do any 2 digit multiplication in less than 1 sec.
