The listing, $100 TEXAS INSTRUMENTS GRAPHING CALCULATOR -- SUPERB USED CONDITION! A MUST HAVE TOOL FOR SCHOOL! has ended.Texas Instruments TI-83 PLUS is used but in excellent working order. I bought this for my daughter as required for geometry and algebra but it is no longer needed so I want to pass this along to someone who has a need for one. I paid over $100 for this brand new and wish I had found it on Listia, but didn't. Many high schoolers need a graphing calculator for their math classes so this will come in handy! It comes complete with protective cover which slides down on the face protecting it. The cover has some light scratches but after being hauled around in a backpack, it's no wonder!
