<p>What calculator would you recommend? TI 89? Thanks.</p>
<p>hmmm...a normal scientific calculator will do the trick. Actually i dont thing you really need calculators. 105 didnt have calculators (they werent allowed).</p>
<p>I didn't have to use a calc for 106. In fact, they were not allowed for midterms and exams. More useful for physics.</p>
