I use my iPad for note taking in my statistics class and I need to create an overline for the sample mean (which has a line over an x called x-bar) and I can't find a way to get it to work in Pages.

I was able to get the Greek keyboard for all the other math symbols I needed, but this one I can't figure out.

If all else fails, you can just copy this: x̄ – jtbandes Apr 6 '12 at 22:00

If you search for "math symbols" in the app store, you will find a number of apps designed to create such things for pasting into other apps. Otherwise copy/paste from an existing note is solution I think.
