Hi julie,

Design science Mathtype is an interactive tool for Windows and Mac that allows the creation of mathematical notation for word, web pages, desktop publishing, TeX, LaTeX and MathML documents. Mathtype is the professional version of the equation editors in MS Office.

Julie, have you already committed to any layout option: TeX, Quark, InDesign, or Scribus? If you’re working in TeX, John’s correct, continue with TeX. If you’ve invested in Quark or InDy, or even Scribus, it’d be foolish to dump your investment and then have to invest the time into TeX. Quark and InDy are far easier to learn than TeX--not necessarily because they're inherently better--John will say TeX is; I'll say they are. If you have publisher clients--aside from self-publishers and academic presses--you’ll likely find they want the native files, so they can have a look. They will prob’ly regard TeX too esoteric a choice for their liking. If you haven’t made a choice and the money isn’t an issue, odds are you’re in for an easier learning curve with one of the WYSIWIG programs. I know many people feel no need to have the instant response of seeing how something they’re doing looks; I just think it’s easier to not work in the dark, but--phonetically, now--saw-zeetch his own.
