Help with calculator, TI-89, fo SAT Math 2!

<p>Hey guys.</p>

<p>I'm taking the SAT Math Level 2 this coming June.</p>

<p>While, I was going through some practice tests, I found out that my calculator didn't want to solve for log. It always comes out as "too many arguments" and when I try it on another calculator, it works. Any of you guys know a solution for this?</p>

<p>Thanks!</p>
