No doubt it is completed now?
I wonder if you would like to share your findings with us.
I'd rather not have another tooth pulled out so I can re-remember it!

How do you do long multiplication and division, with or without having a wisdom
tooth pulled? I am just trying to understand. :-)

You do long multiplication - eg -

64
64
64
64
64
64
64 +
448

or if you prefer:

7
