I just bought a TI-84 SE. I have a week. What should I learn to use for the SAT?

<p>What functions on this calculator should I get familiar with before I take the SAT next week (yikes)</p>

<p>graphing to solve equations</p>

<p>Yeah, graphing would be a useful thing to know how to do but, in all honesty, just using it for arithmetic will suffice for the SAT.</p>
