Title: Student Beware
Product review: *This is not AMAZON'S fault, complain to TI @ 800-TI-CARES (ya right)If you are in grade school thru Algebra I, this calculator is overkill. If you are in Pre-Calc or beyond this calculator is WITHOUT VALUE of any sort. TI informed retailers that the nSpire has the ability to perform Variable Algebraic and Calculus problems. That is a lie. It WILL perform a "Numeric Derivative" as if that would be helpful to anyone who can find a tangent to a point. TI has failed to differentiate between this model and the similar CAS model. Further scandalous activity is the fact that the CAS model is not likely to be admitted to standardized tests, but you WON'T FIND test approval on the same comparison showing the differences between the CAS and the base nSpire.
