nothing more than a pencil is _needed_ for all the math you'll ever do, but
the point of the 92 is to lower  the time it takes you to do something.
Unless the teacher rigs the questions so that all the computed values are
nice and simple, the 92 helps alot.  I'm not suggesting that you shouldn't
know the underlying principles of what's going on, but I sure as hell
wouldn't want to do a de assignment without a 92.  There's several people
in my class who aren't too fluent with a 92 (everyone is reqd to have one),
but it's just agony watching them grind out stuff by hand, which can
usually be accomplished in a couple lines of ti.  As long as you can still
show how to do stuff if the teacher asks, then you'll be better off in the
long run with a 92.

BTW, I live in canada, so the stuff about sats doesn't really apply to me.
I guess the 89 is good if you're not allowed qwerty, but if they're easy
enough to do in your head in the first place, all a calc will do is let you
finish in half the time.  And on a test, that's not really that useful...
