<p>When I do a problem such as 3(10^-4) I get 3 e-4 instead of .0003. I have it set to normal and float. How do I fix this?</p>
<p>The TI83 gives up showing all the decimal places and goes onto scientific notation mode automatically after three decimal places. It will show three, but not four. So you can't really fix it unfortunately.</p>
