no' date=' the 84 lacks a computer algebra system, in other words it doesn't really understand the operations that you put into it, the 89 does.

 

the other advantage of the 89 is that all of the functions are keyed into menus that you can access with the touch of a button, so you can change settings and find solve functions within seconds in a nice graphical interface.

Thats what im looking for, something i can punch right in and get a quick answer.

But im guessing that my Teachers wouldn't like that ideal, or would they let me use it?

the 89 can do all of the things that an 84 can do' date=' and a bit more.

 

probably the most useful feature on it that I've found is that it displays symbolicly exactly what you entered into it in linear form, for example

 

if you enter in

 

(1-5/2)^-4

 

it will show this to you

 

[math'] \frac{1}{(1-5/2)^4} [/math]

Is there a program I can download to the 84 to make it do that you think?

My calculator is mostly used for addition, subtraction, multiplication and division, I think I've used my brothers liberated graphical calculator once since starting uni... Have you checked to see if your college has a list of allowed calculators for exams? It's sometimes the case you'll need a more basic one...

Yep they allow that 1. My cousin told me that most people there use the 83+.

I was thinking about getting the 89 but look at the comparison between the 84 silver edition and the 89. It dont look as if it can do the Algebra 1&2 and Trig etc.... I may be looking at the chart wrong though think. Will it still do all the stuff the 84 silver edition does? take a look.

Im thinking about about getting the TI-84 plus Silver Edition, Its only 9 more dollars than the regular TI-84 plus and quite a few more features.

I live in the U.S. btw. Thanks for the help guys, i really appreciate it.

I am fixing to start college and I need the best allround scientific calculator.

I will probably be doing a little Algebra Geometry and Trig.

What would ya suggest?
