<p>is it legal to put equations in your calculator and use them during the SAT?</p>
<p>I wouldn't. It would just slow you down.</p>
<p>no, it's not illegal</p>
<p>are you sure?</p>
<p>You can use anything... if you programs which you think could help you, you can use them... although I can't think of too much which might help... </p>
<p>If your calculator doesn't have a built in equation solver, though, I'd recommend getting one, as it could save you some time.. or buying a TI-89 (even better) :-D</p>
