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).
Should be Typed

That means that you know your calc crashed. This can be caused by taking out the batteries durring running time, happened just randomly. Well nothing to fear just press clear and it should go away but if it stays on that screen you have problems and is best to try some of these methods. Take out all the bateries and press and hold the on button for 30 seconds. Put the batteries back in and it should have reset. Warning you should archive everything incase this happens. To archive go to 2nd mem and hit enter to put a astrick next to the app (meaning archived)

I'm not specifically familiar with the TI83 or TI84 but I've used a lot of TI calculators in my time, so I'll give it a try. If your trying to find the antilog of a number in base 10 enter the number and hit the (10 to the X) button. If you're trying to find the antilog of a number in in base e (natural log), enter the number and hit the (e to the X) button.

Press [MODE]. Use arrow down to go to second line Float. Use left arrow key to move cursor to a number other than zero and press [ENTER]. If you highlight 2 your results will have 2 decimal digits, but if 0 is highlighted all results will be integers (no decimals).
Hope it helps.

Testimonial: "Thanks for all your help. The tips were very helpful."
As battery gets drained, the screen contrast dims. But when you change batteries, some times the contrast is reset to some low value and the screen appears dead: it is so light that you do not see anything, and you think the calculator is malfunctioning. This is the most frequent reason users think the calculator refuses to turn ON. And I hope that is the case now.
To correct that, you must increase screen contrast: draken the screen a bit. To do so
