You dont need to draw it all the time if you understood what he does...for example 187*199 is way too big to draw it....
He's just doing it that way (Example 187 * 199)
1 * 1 = 1
1* 9 + 8 * 1 = 17
1 * 9 + 8 * 9 + 7*1 = 88
8 * 9 + 7 * 9 = 135
7 * 9 = 63
Now you get the results and do it the way he does, from back to beginning...If there are more than one number, the first one jumps one up...You ad the 6 of the 63 to the 135 so its 141 and you go on like that...
Result: 37213
