  1. do you mean the normal longhand method of multiplication, or some sort of mental trick to make it easier?

    If the former, then just google your question and you will see various explanations of multiplication by hand.

    If the latter, better minds than mine will have to help. None of the shortcuts I have learned seem to apply here.
