Hello Folks, I lost my black Ti-89 calculator in the 101 room in the Sondheim building last week Friday, after my Chemical Thermodynamics exam. I  have gone to the "Lost and Found" section in the Commons building but they haven't received it either. This calculator is really important to me, due to the programs I developed in it and also for my upcoming exams. If found please be compassionate enough to drop it off at the Information desk of the commons building or email me @ Sheri4@umbc.edu to return it.
