Tricks 3
In such
cases, n zeros are put at the right end of N to get a new number M and then M
is divided by 2n to find the required result of multiplication.
EXAMPLE;
FIND THE VALUE OF 9482*25
SOL. HERE N=
9482, 5n =25=52
Here n=2
According to
the rule ,
(N) (5N)
(M)
9482*25=
948200/22
=948200/4=237050
HERE n=2
hence two zeros are put.
M has been divided by 22 as n=2
