If anyone who has a Prizm could answer the following questions, it would be greatly appreciated.1. Can it simplify fractions like (1/2)+(32/7)=71/14?2. Can it do prime factorizations like factor(221)=13*17?3. Can it add nth roots like (3*root(2,8))+(5*root(2,2))=11*sqrt(2)?4. Is input handled as well as it is with mathprint on the TI calcs?
1) Yes. However you need to use the ab/c button instead of (1÷2)+(32÷7) to get your result. The calculator can display it in two different modes, so it may come out as 5(1/4) rather than 71/14 though, depending on your settings.2) Not without a program. I've attached such a program below 3) Nope. It can only return the numerical answer.
Some T3 teacher said (probably without reading/understanding anything) we were responsible for all this, as we were using unauthorised OSes and encouraging their use on TI-Bank...
This is just sad. Texas Instrument's quality control has been lacking for years, and it only seems to be getting worse. It amazes me how many issues they've had with the Nspire since it's release.

Yeh, about now some teachers have to be wondering what they got into by buying nspires and navigator systems for their classes only to find that OS 3.0 and nspire cx made all that obsolete. I mean they could have went the safe route with 84 or the more recent Prizm and saved all those head aches. It looks like ti's quality control problem is that they don't have any quality control. The business model seems to be "throw it out there, let the customer find out if it works, and fix it later." Wonder what cx problems will be discovered when it becomes available?
I have installed the official release of OS 3.0. But I did battery pull more than 5 times while I was testing Lua programming.
They're just stupid. I guess they put blames on us whenever stuff happens. Well... they'll see in a few years if we unite with Cemetech boycott of the TI-Nspire CX and that almost no game are being produced for the new OS and students decides to go with calculators that they heard there were games for, such as the Casio Prizm or older TI-Nspire calcs.QuoteDo you REALLY run Windows 3.1???
I'm afraid so.
His computer was, most probably, made during the first half of the 1990s At work, last year, I reassembled several ISA cards into a motherboard bearing a soldered AMD 386 SX 40, plugged one of several 52 MB HDDs with DOS 6.x & Win 3.1... and for good measure, a trackball, whose drivers are on 5"1/4 floppy disks labelled "Logitech 1989". Most parts were made in the first half of the 1990s.
