Texas Instruments TI-Nspire CX II Color Graphing Calculator with Student Software (PC/Mac) White 3.54 x 7.48

It has arrived on time!

I love that it shows line for line what calculations the user has completed!

First, let me say that buying this refurbished was probably the most economical way to go about it. How TI calculators get away with being so expensive and doing so little compared to a much smaller and more feature-rich smartphone, I never will understand (aside from palms in the testing industry getting greased). The calculator itself works well and is easy to understand and use after going through a few video tutorials on YouTube. The battery life is impressive (measured in weeks or months as opposed to hours or days with a smartphone, even with daily use). But value? Come on--over a hundred dollars for something with less power than the smartphone I had a decade ago?

This calculator is nearly impossible to learn to use for a teenager who isn’t interested in math in the first place. There are online free graphing apps and websites that are far more user friendly which makes learning math and graphing much more pleasant. Waste of money for us.

Got this for my son and he loves it.

This is exactly what my daughter needed for school. A great price too.

Son picked this one due to ease of use

I wish I had read the details more carefully and even the questions, because those state this calculator does not have CAS. But, a person should be able to rely on the description listed by the seller.

My mother bought me this as I am a sophmore in college and my basic calculator couldnt help me anymore and I love it. Also since I see a few questions about the difference between the TI Inspire CX II and the TI Inspire CX II CAS is that the CAS can solve algebraic functions and factor basically like Mathway. This is why the CAS version is prohibited in exams such as the ACT, SAT, AP, and many college classes. A close friend of mine has the CX II CAS and is prohibited from using it in her calculus and stats class and is struggling now because she was using the CAS system as a clutch. My recommendation is if youre a highschool or college student, you should get the CX II for school because you can use it in class and on exams and use the CX II CAS for home or work use.

Si solo quieres los vales en número como por ejemplo 6x2 o calculo definidas, te servirá por qué solo da resultado numerocios pero quieres algo como 6 por 9x o parecido no te dejará el cálculo con variable, para eso cómprate su versión que diga CAS
