I have expressions which are a product of about 5 things and they are output with excessive parentheses, for example: (((1+a)(1+b))(1+c))(1+d) The parenthesis check in the code just adds parentheses if the left subexpression contains a minus or plus. Of course, it should check if there is a minus or plus that isn't already bracketed or something like that. Would you like a trac bug for that? In any case, the latex view functionality is IMO a huge feature of sage that I've wanted in so many other systems. It's an absolutely essential alternative to the screenful of symbols which are output from Maple/Mathematica and others when stuff gets big (of course, maybe I'm missing some features in the big M's). -- Joel --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://sage.scipy.org/sage/ and http://modular.math.washington.edu/sage/ -~----------~----~----~----~------~----~------~--~---
