<p>If you really need the help in calc. you should look at the Texas Instruments TI-92 Plus Graphing Calculator. It solves any calc problem!</p>
<p>Yeah I heard about that thing...very nice. I think it uses something called a symbollic processor to do the work..however, I would like to learn calc myself not just solve the problems.</p>
<p>Calc is amazing. You def. should learn it at any given moment in time. I rec. you use the cal, as a supplement not a substitute</p>
