Such a practice can propagate a roundoff error, and while that is admittedly not often a material concern, there are certain problems where it comes up.<br /><br />It's tougher to avoid this if you just have them using a regular scientific calculator, and I don't permit graphing calculators in Algebra class, so I don't know what to tell you.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-10348701.post-43274107894197657232010-03-20T08:45:21.570-07:002010-03-20T08:45:21.570-07:00My students were THRILLED when I gave them permiss...My students were THRILLED when I gave them permission to use the calculator for the stats chapter.<br /><br />Then they saw the formula. Now they're not so thrilled. ;)<br /><br />They don't bother asking me to round anymore... my usual response is a very sweetly voiced "oh, is that too easy? Well, if you REALLY want I can change it so you do it by hand!" At which point, the rest of the class shushs the lazy one.
