Personally, I
say every kid should be armed with a basic scientific=0A=

If you don't understand how to do basic arithmetic by hand, how are you
goign to understand how to multiply and divide polynomails in algebra?
The methods are precisiet the same as long multiplication and division of
numbers
If you don't undertand how to add up multi-digit numbers, how will you
understand waht a 'carry flag' is? How will you add up `128 bit numbers
on your 32bit CPU (or whatever)?
Use infinite precision math libraries in various languages (lisp being the
obvious one). ;-)
By all means use calcualtors. But engineers -- especially -- should
understnad how they work.
I don't disagree with what you're saying...just couldn't resist pulling your
chain. ;-)
