Question 1

is it better than the ti-84

Accepted Answer

The black TI-89 is older than the TI-84.  It has the computer algebraic system which is able to do a lot of the algebraic processes with the calculator like factoring, expanding, etc.  It is great for Calculus when you already have your Algebra skills mastered.  The TI-84 is more useful for other subjects, particularly Statistics.  It just depends on what you need the calculator for to decide which is better.

Question 2

is the calculator purple?just want to make sure before i buy because the picture is purple

Accepted Answer

it doesn't matter the purple color the problem was the color of different function. they were written very much similar to the back ground color which makes harder to read i have seen a clear picture and get darker one .i remember dark green on black.

Accepted Answer

The one that is pictured is the original...but, I purchased the Titanium version for my son.

Question 4

does this calculator do inequalites, does it also do nth root and log root etc basically does it have all the features of a titanium

Accepted Answer

Don't buy this model. It is outdated by more than 10 years. The main difference is the quantity of memory. Titanium supersede it 10 years ago and costs much less. The colors shown on the photo are not actual. Buy a Titanium for +/- $120. Titanium does everything for algebra, including inequalites, nth root, log, Ln, solves systems of several variables, matrices, integral, derivatives. It is really a dream. I had to return it and got a TI-89 Titanium. To have it clear, go to TI site.
