Texas Instruments TI-Nspire CAS Graphing Calculator & Cover - Tested & Working

Texas Instruments TI-Nspire CAS Graphing Calculator & Cover. Tested and works perfectly. Works with 4 AAA batteries which I can include if you want. Took some screenshots of the screen to show it working doing different things. Very expensive calculator when it came out in 2007 and this CAS programmable calculator is good for beginner math all the way up to calculus with the higher math equations. Very good condition (as seen in pics) considering it came out way back in 2007
