Ti-89 my nig. More memory for storing sweet mega man clone games.

I was talking graphing calculators with a friend and he said he either was going to get a TI-89 or some kinda tablet, or touch pad thing. I think he said Casio or something. I don't really remember. Anyone know what I'm talking about and if so is it any good?

That's just plug and chug. You're golden if you know what a variable and a constant are. I'm pretty sure the average 13 year old in the US is doing this.

This would work if you completely ignore developmental levels and choose not to educate everyone.

Common Core math is actually more robust than that.

My 89 is over 13 years old. It was well worth the $180 investment.

I have a Calculus final tomorrow which I think I might fail since the instructor is an ESL TA who sucked at teaching. How much will using one of these improve my score on the final? And where can I find one on such short notice?

I'm forced to buy a graphing caculator for school. I"m stuck between the T.I 83, 84, 89, and the Nspire...Whats the difference between these assholes? I know the Nspire is pretty new, whats it got that the other 3 don't... What's your favorite?
