Expanding each integer in the expression 21 x 12, the result is [(2 x 10') + (1 x 10°)] [(1
* 10') + (2 x 10°)]. Replace the 10s with x's and then multiply this expression using FOIL.
Compare it with the normal integer multiplication method used above: How are they
similar? Show your work. I’m so confused
