Just a piece of advice, if you plan on importing and exporting documents into and from PC formats, Documents to Go is the better choice in Word Processing. Pages DOES export to MS Word format, but Numbers and Keynote do not, and Pages tends to screw up formatting from MS Word on import. However, Docs 2 Go doesn't have that function, at least that I can see. The word processing app is lacking. I also re-downloaded Pages just to see for you and I don't see what you are looking for either...are you trying to basically insert an equation like you would use in Excel?
I am not trying to get a working formula. I write some mathematical texts and just need the ability to write the functions or equations. I need exponents, I need subscripts, I need a fraction bar where I can have a polynomial numerator and denominator etc. I also need the Greek alphabet.
Unless I'm missing something, I don't see those options in either one of the programs. Greek letters you can get on the iPad keyboard regular if you hold the key down, I believe.
Your right about the Greek alphabet. With no equation editor Pages is of extremely limited value to me I'm afraid.
I just checked, Google Docs has super and sub scripts. It also has special characters. Try it and see if it works for you...should work in Safari just as well...
No clue if it works with iPad, but have you looked at mathtype? Edit. The website says it works with iworks.
I did a little searching myself and saw MathType mentioned a lot with iWorks. apparently there is no MathType app for the iPad yet though. The thing I find odd I'd that MathType is not an Apple product. Apple"s proprietary word processor not having an equation editor is really strange. I just started playing with Pages and there is a lot to like about it but what a gaping whole they left.
No way to do that in pages now, but there is an app that lets you typeset equation in TeX, then copy the equation image over to pages. search for "TeX Equation" in itunes.
