The calculator at this site will multiply these two number for you.

 

However, you needn't multiply the entirety of the two numbers together to get your answer; all you need to do is multiply 89 x 21.

 

89 x 21  =  1869; so the last two digits of your answer will be 69; any digits before the 89 and the 21 will not affect the last two digits.
