There is no button, otherwise you would have discovered it. However you

You MUST put parenthesis around fractions in a TI-83. If you have a fraction with multiple parts in the numerator or denominator, you MUST put parenthesis around either the numerator or denominator (depending on which one has multiple parts).

E.G.:

X*Y-L/N

Should be Typed

((X*Y-L)/N)

My calculator got sprinkled with rain... i think... I just saw that it had water on it, and it was in my purse, but it was raining today. Anyway... now it wont work, I can only press the on key. It is the only one that works. How can I get my keys working again, barely any water was splashed on it, it cannot be broken!
