Texas Instruments TI-30XIIB calculator

This is a great basic calculator. I'd recommend the solar powered version though since its the same calculator and you don't have to worry about replacing the batteries.

This is a great non-graphing calculator. It's got all the features I need and is easy to use. What else is there to say about a calculator.

Mine is blue. There's no cover to it but that's fine. Works great and is perfect for pre calculus

the buttons are a little sticky, but for the price it is absolutely wonderful, glad I bought it, good instrument, and not batteries to deal with !

Works well, but the lid didn't come. Kind of disappointed. Otherwise, great buy especially on a broke college student's budget.
