[challenge] Multiply two numbers like on paper

Question

Multiply two numbers with more than two digits each.
Your program should only be able to multiply one-digit-numbers.
so 343 x 281
1*3+1*4 add 0 + 1*3 add 00

for adding 0 it is allowed to multiply with 10

Additionally think about a program that only is able to add to one-digit-numbers.
