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

It is very useful and it works very well and it easy to read.

Perfect for college

Solve function doesnt work for higher level math (Schrodinger Equation for 1 electron)

As expected

Works great

Got this for my daughter and she loves it

My little brother loves it!

Easy to use

Powers down randomly loses all of the current work and constantly says its charging even when its not plugged in

Great purchase
