Pretty print fractions, and especially pretty print n roots seem to be more costly in # characters allowed and acceptability. Classic entry of fractions and fractional powers seem much less restricted...so much less so that I prefer setting the equation up in table to verify that the function behaves as I expect, and find reasonable guesses. Then, it's a snap to go to num-solve, set 0=d/dx then hit table, choice 1 to enter f(, make it f(x), and solve for x=x. Easy then to find f(x) for critical points found.

Quite the illuminating point. Perhaps there is some more intensive memory/punctuation token demands in MathPrint than Classic that is not evident in the manual.

Thanks for that behind-the-scenes tip.
