Heya!!!
= 107 × 93
107 can be written as (100+7)
-----------------------------------------------
93 can be written as (100-7)
-------------------------------------------------
Then,
107 × 93
= (100+7) (100-7)
As, (a+b)(a-b) = a^2 -b^2
= (100)^2 - (7)^2
= 10000 - 49
= 9951
HENCE, the answer is 9951.
