Question

evaluate the following products without multiplying directly 104 multiply 96

Answer 1

We can write 104 as (100+4) and 96 as (100-4) so new question is (100+4)*(100-4) that makes property a
${ a}^{2} - {b}^{2}$
Thus solution is
${100}^{2} - {4}^{2}$
=10000-16
=9984

Answer 2

104×96=(100+4)(100-4)
using identity=a^2-2ab+b^2
(100)^2-2(100)(-4)^2+(-4)^2
10000+800+16
