TI-84. Edit: You can work with a TI-83 plus, but a few of the Stats buttons won't be on there, which annoyed me for my Stats exam.
Don't think you'll cope all that well if I'm honest. You'll need a fair amount of effort in HL and if you lack the drive, then you might slack off.
My school recommends me the TI-84 as well. It costs about 80 - 125 US dollars depends on where you would get this. If you are familiar with Ebay or Amazon, don't bother to look because you could find a great deal!
TI-84 plus silver edition?
how long does amazon send the items to your place anyways...
im trying to order one but im not sure whether it will arrive on time..
i know its cheaper too
I would go for TI-84 Plus or TI-83 Plus. Both aren't bad...but if you want the best calculator...I guess you should go for TI-84 Plus. It's pretty expensive though.
I think it is more important that you try and use the same calculator model as your teacher (or, failing that, use a calc from the same "family", e.g. teacher uses TI-84+ Silver, you use TI-84+) so that it is easier to follow along when s/he demonstrates functions on the calc. Personally I am very happy with my TI-84+, mostly because my teacher also uses this model and I can follow her exact instructions when learning new calc functions in class.
Quite often math textbooks use a certain type of calculator as reference or as a supplement to the text. I would, therefore, recommend you to buy that calculator. There's probably a good chance that your math teacher has the same calc. because he/she most likely chose the book. Anyways, the Ti's are the most prevalent and it's fairly easy to get hold of new apps, which, if anything, makes me prefer those.
I would say buy a TI-84.
You will not regret it.
And good luck with HL maths. You will truly enjoy it. SL Maths is an okay subject. But it stops just when it gets interesting.
i would say buy a TI-84 plus silver edition.
there are more math formulas inside that calculator and chemistry formulas if youre doing chemistry.
TI-84 + Silver Edition. It's no joke the best calculator ever created on this planet.
++ It's so pretty! AND you can play tetris! :P
ti-84 plus comes with software that can help with portfolios if you don't know how to use cas programs, and the interface is easier to use vs casio graphin calcs. Treat your graphing calc as an investment because it'll come in handy later on in uni if you do anything that has to do with maths. Ti-89 calcs are not allowed though but then they are significantly harder to use than the Ti-84s.
