Multiplication is the shortcut for showing a repeated addition:
1 x 36 = 1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1
+1+1+1+1+1 = 36
2 x 18 = 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 = 36
4 x 9 = 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 = 36
6 x 6 = 6 + 6 + 6 + 6 + 6 + 6 = 36
