<blockquote><font class="small">In reply to:</font><hr /><p>Yes, that is what calculators and computers are for.<p><hr /></p></p></blockquote><br /><br />Calculators are invaluable for arithmetic; when it comes right down to it, an aptitude for 6th grade math really isn't all that important even in the most advanced of science disciplines, although all us laypeople tend to confuse arithmetic with the really interesting stuff in math. What you really need to understand are the *concepts* of mathematics. Use the calculator for computation, but understand how it works, when to use it, and what equations to plug into it. That's what's important in math. Being able to find the square root of 15834 in your head is a neat trick, and it's good to be able to do it on paper if you have to, but what's really important is being able to understand when you actually want to know what the square root of 15834 is. <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em> -- The Tenth Doctor, "Blink"</font></p> </div>
