calculator
I miss my calculator. It's a TI-83 plus silver edition. If anyone sees it laying around, it's mine! I need it for my chemistry exam tomorrow. I already know that 4 out of 25 questions will have numbers, but for those 4...it's a little more than math you can do in your head... or at least that I can do in my head, or on paper for that matter. I'm really bad at logs and antilogs, and division. :( My brain hurts. It's about 10 hours til go-time, and I really SHOULD spend that time studying or sleeping, but I spend it looking for my fucking calculator.
