Answer 1

Answer:

answer is 9801

Step-by-step explanation:

so,

take this 99 as (100-1) and do the same to the other 99.

so, now you get the following steps to solve this. good luck.

(100-1)*(100-1)

now, first multiplying hundred,

(100*100)-(100*1)=10000-100

now multiplying -1,

(-1*100)+(-1*-1)=-100+1

this ends up like:

10000-100-100+1

10000-200+1

10001-200

9801

here's your answer without actual multiplication
