Use Grapher to embed equations in Pages and Keynote Apps
There is no equation editor available in Keynote or Pages, but it is possible to creat nice equations in the Grapher application (in /Applications » Utilities) included in OS X, and then copy/paste the equation(s) into Pages or Keynote.

However, I don't know how to select a font color to match Keynote's master. Perhaps there's a better/free way to create nice equations to use in Keynote and Pages?

Use Grapher to embed equations in Pages and Keynote

You can change the font used. Go to Preferences and click on the the Equations button on top. Click in the "Default Font & Size" window and the standard OS X Font chooser window will pop up. You can select any font and size on your system.

Yes there is. Get Latexit.
http://www.macupdate.com/info.php/id/17889

Actually, it presumes you have a tex installation, but you can just install MacTeX which is really easy to install, includes a full tex distribution and latexit:
http://www.tug.org/mactex/

It allows you to type the latex equation, and it will generate a little pdf with just that equation. You can then drag it into keynote, powerpoint, etc..

For those unfamilar with Latex, it allows to type equation with syntax such as:
w^{n_{\log_2 m}}
which would be w all to the exponent of n with a subscript on the exponent of log base 2 of m. That kind of thing. It's got different fonts/sizes, any greek symbols, about a gazillion operators, etc..

Texfog (http://homepage.mac.com/marco_coisson/TeXFoG/index.html) is a GUI for the formula editor - brilliant stuff

Use Grapher to embed equations in Pages and Keynote

If you know how to use LaTeX, I use LaTeXiT, which produces beautiful PDF format (or other image format) equations, and you can control size and color from within the program, and use LaTeX to vary the font. If you don't, it really isn't that hard to learn; try this introduction (PDF file). To install the LaTeX back-end and various front-ends (TeXShop and LaTeXiT) with minimal hassle, the MacTeX package is the way to go.

I second this! Plus: if you export PDFs from LaTexit, they retain the text used to create the equation for easy editing later! YAY!

I use EquationService. It hasn't been updated for a few years, but it works just fine. You need to know latex too, but it's got a nice output window, so you can just use trial and error till you get your equation right. Then just drag and drop into Keynote/Pages.

Equation Editor or LatexIt
Authored by: zacht on Mar 28, '07 08:25:21AM
Three (old) hints on this site:

As others have said, there is now a new program called LatexIt which looks very nice. (I've just started using it recently, and so far, so good.)

When I'm writing quizzes and exams for the math classes I teach, I like to make graphs in Grapher. I use Equation Editor or LatexIt to generate equations. I use drag-and-drop to copy the equations into the Grapher window. Then I export the Grapher graph as a PDF, and include it in Tex using an \includegraphics command. Grapher allows you to change the color and style of curves and points in the figures. I don't do this myself, but it is possible to make the equations different colors as well, using Latex's color package. (Google for "latex usepackage color".) (I don't use color much as quizzes and exams are printed black-and-white.)

It is possible to change fonts in Latex. Google for "latex usepackage fonts". The support is not as simple as one might wish for. In Equation Editor or LatexIt you will have to edit the preamble. Commands like "\usepackage{times}" or "\usepackage{palatino}" (in the preamble) will change the font for text, not for equations. Here is a web page with very good information about math fonts:

http://ctan.tug.org/tex-archive/info/Free_Math_Font_Survey/survey.html

(I didn't know about this till I was writing the last sentence! :-) )

The copied data is just PDF, so you can paste it anywhere that will accept a PDF graphic, including Preview's "New From Clipboard" command.

Use Appleworks
Authored by: Scripter12 on Mar 28, '07 05:28:32PM

Many of us still have old copies of Appleworks. Under the Edit menu is an option to insert an equation. It brings up something called Equation Editor. Not the greatest but if you have it it's free. This gives you some control of the appearance before you copy the equation to Keynote or Pages.
