It's a lot easier to use. The TI-83 requires the user to remember a lot more. It uses parentheticals to enter data, so the user must enter the required data in the required order, but there is no prompt. The TI-84 gives prompts for required data points such as mean, median, z-scores, critical values, etc. It also has more data packages than the 83, so less work has to be done manually. I'm kind of glad my 83 crapped out so I had to replace it! :-P Hope that helps.

Can this be used for Algebra through Calculus in high school?

Yes it can. Many of my customers are high school / college students. They mainly use it for calculus and statistics all throughout their school career.

Is this allowed for sat/act tests?

This is allowed on both the SAT and ACT tests as well as AP exams.

will this calculator fit the needs for all math? (calc, algebra, geometry, etc...)

is this good for high school geometry
