I always hated arithmetic. A little set theory might have done me well in elementary school. Ahh…ok…Seems like it might have been interesting, if done well. I always hated arithmetic.

Bases other then 10 and set theory was taught to primary students. That's where the whole octal subtraction part comes from. For the base 10 subtraction the difference was in how it was explained. There was a great deal of emphasis placed on the fact that 40 is '4 tens' and '1 ten is 10 ones'. Rather then saying 'you borrow one from the next column to give you twelve'.

Is there some secret, non-borrow-a-one way that my teachers didn't share? Tom Leherer’s movie is pretty funny but isn’t that how everyone does subtraction?
