Question about Texas Instruments TI-83 Plus Calculator
My Texas instrument TI 83 Plus calculator will not turn on. I have replaced the batteries with new ones. I have also taken out the lithium battery out and put it back. I had gone to the Texas instrument website and have tried everything they told me to fix it.
TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible. If this doesn't do it, please reply to this post and we'll go on from there.

The division sign acts like a fraction on the ti-83; to multiply two fractions you may want to wrap them both in parenthesis to get the order of operations correct.
