Re: A92: TI ANNOUNCES NEW CALC!!!!!


You are required to have a 92? Hhm! is this a private school?
I have nothing against doing tedious calculations with a calculator, that's what's
it's for, although mental arithmetic isn't emphasized nearly as much as it ought
to.  But I've found that when a calculator starts to replace conceptual knoweledge,
it becomes dertimental.
