You multiply right to left and each time you finsh a line you add a zero to the answer.      

Ex.

100

x 100

---------

000

+00001

----------

10,000

Thanks for that resource, Melody.....I saw this question earlier, but I didn't know how to proceed with a good explanation.....that website looks to be pretty informative......multiplying "by hand" seems to be a lost art !!!!
