no two individuals are the same and as such it is next to impossible for all persons to become human calculators,

well that may be true for thoose who don't try but there are ways to do large multiplication by only considering simple sums. Take 217 and 556 for example 1st 6*7= 42 2nd 1*6 + 7*5= 41 3rd 6*2 + 7*5 + 5*1= 52 4th 5*1 + 2*5= 15 5th 2*5= 10 By putting these steps together 42 in first units 41 in second units 52 in third units 15 in fourth units 10 in final units giving 120652 And thus difficult multiplication through basic steps
