In lesson 15, for multiplying 204 with 107 ,Iwe used base as 100. Can we do it with base as 200 by first multiplying 107 by 2.?I tried this way.
base =200 204 +4
218/56 and if we do half of it (since 107 was doubled)we will get 10928(not 10914).
But with base as 200,if we multiply by 2(i.e.218*2),we will get 43656 and then again need to half of it giving the answer to be 21828.(however if we still make it half,will get the answer). Please explain if we can do it with base 200 and where I am getting wrong?
