As we could "drag" these together, we could then do it the easy way.

  56
+56
+56
-------
168
------------------------

Or we could also do the following:

56[tex]*[/tex]3:

6[tex]*[/tex]3= 18.

Carry the one. 

5[tex]*[/tex]3 = 15+1 (which was carried). = 16

(16+8) = 168





where is the picture :) ?
