295*305
295*305= (300-5)*(300+5)
295*305= (300-5)*(300+5)= 300^2 - 5^2 .........( (a+b) (a-b) = a^2-b^2 )
295*305= (300-5)*(300+5)= 300^2 - 5^2 .........( (a+b) (a-b) = a^2-b^2 )= 90000 - 25
295*305= (300-5)*(300+5)= 300^2 - 5^2 .........( (a+b) (a-b) = a^2-b^2 )= 90000 - 25= 89975
hope it helps :)
