**MULTIPLY TWO NUMBERS WHICH ARE NEAR 100(2)

if the given nos are more than 100
take that two nos---
at first subtract 100 from those number
now, the first three digit of multiplication result will be (any given no + another's subtraction result )
and the last two digit will be multiplication of those two subtraction result

...........................................................................................
EX:-
104*103=?
here 104 is 4 more than 100 and 103 is 3 more than 100
so the first three digit will be (104+3) or (103+4) or 107
and last two digit will be 3*4 or 12
so the ans will be 10712
