With calculator, graphing, geometry, list, spreadsheet, data, statistics, notes and vernier dataquest functions, this Texas Instruments TI-Nspire N3CAS/CLM/2L1 handheld calculator serves as an ideal learning tool for a wide array of applications.
I'm an engineer student and needed a CAS calculator. I'm going to be using this calculator for YEARS so I hope this one makes it. So far it works great. Battery last long time (have only charged it once). Only reason I did not rate it 5 stars is the price, very expensive for a calculator. I would not reccomend it to a friend for the same reason, too expensive. I'm sure you can find a cheaper one that does the job as well as this one.
