Question about Texas Instruments TI-83 Plus Calculator
Sorry, but you cannot calculate percentages at the pressing of a key. The calculator does not have a key for that. You will have to do it yourself.
To convert a decimal result to a percentage, multiply it by 100: MOVE the decimal mark two places to the right.
To convert a percentage into a decimal number, divide the number by 100: MOVE the decimal mark two places to the left.

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

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)
