I'd like to be able to insert mathematical formulas into Word or Pages. I don't necessarily need professional-looking output -- I'm not presenting this stuff to anyone. All the Latex editors seem really complicated. I've tried Lyx but I keep getting error messages. I'd prefer not to have to download 10 different programs. I've heard AppleWorks has an equation editor -- is it very good? I need to be able to do multivariable calculus, linear algebra, and statistics (e.g., integrals, derivatives, summations, matrices, etc.) Thanks for your help!
