if you can afford one get a TI-89. It will put the 83 to shame and make your life so much easier.We were required to get one in Grade 9. I have a TI-83 Plus.

They let you use a CAS calulcator for calculus?!?!? Back when I did it in year 12 we had 2 exams, one calc free one with a non-CAS calculator
Although I do have a Ti-83 Plus still, the most fun thing about the calculator is writing your own programs (on the calculator itself, in it's half-complete TI scripting language)

Yup, but that was in high school. They were even allowed on the AP exam.
Now, there's no calculators on any math exams, but I still use my TI-89 for math homework, and it's especially useful for other classes like physics, where it is allowed on exams.

We weren't allowed graphics calculators in physics either , man you guys get it easy
Well in the classes where my graphing calc was any use to me, the assignment were all worth between 0 and 5 % on your final grade. So it didn't really matter whether you showed your work or not, since it wasn't what decided your grade. The exams did that, and in those you weren't allowed your calculator.Don't they still make you show your work in class?
All in all, in retrospect, it's like the calculator was a trap set out to me from the beginning... (Although I use it quite a bit now. It's a pretty handy tool, but it doesn't make you smart.)
Teacher: "You connect with Internet Explorer, but what is your browser? You know, Yahoo, Webcrawler...?" It's great to see the educational system moving in the right direction
Yes but in my exams for example you still got at least 1 mark for the question if you had the answer (usually out of 2 or 4), also for some things they want you to do by hand, such as simply finding intercepts.
I must be missing something here, but the trap where the calculator does the work for you and not bothering to learn anything beyond that is a completely voluntary one, and I guess most teachers will rationalize that if you can input a problem into the calculator, you must know something about the formula. That should help people cram.
[perspective...]
Not particularly for anyone: I guess it makes a difference whether you're in university or not. A new student will meet professors that he or she doesn't really click with and will not get a lot out of class, obviously. The quality of one's post-secondary schooling still relies on how hard you are willing to work, and it would be the proper time to put forth a personal best effort to learn, though. HTH.
I think it's silly that they let you have the calculator all year and then take it away from you in the final exam... makes no sense.
I know that, but they teach you to rely on your calculator and then they take it away
Talking about calculators I remember that when i take calculus during grade 12, the midterm we cannot use a calculator, I got 100%. In the final we are allowed to use the calculator and its multiple choice, I got an 80%.
Chances are, if your class initially bans using calculator and then uses it at the end, prepare for a good whipping. For us, the final consists of 30 application differential/integral equations all under 1.5 hour, so even with a calculator, you would still need to know your stuff.

The one thing I hated about math is that unlike programming you can't just pick up a "how to" book on it that explains it in way that is structured to encourage self learning. The pre-calc, calc, trig, algebra books i've been exposed to are horrible for self-learning.
