There is a free and a paying version.
Did I mention arrow keys? It has 'em...

You beat me.

Sundry notes is really powerful.
It has a bit of a learning curve, but lots of flexible features.

You can even record and put the sound recording right there in the middle of your note.

Thanks

Cymbol™ for iPad just type in 221A select, convert hex to unicode, copy then paste. √ x˛ and note, there are quick access superscripts that works with iAWriter, Pages, Numbers, etc.

I found a solution. I realize this is an ancient thread, but hopefully it'll help others that stumble upon this.

Copy this radical sign √

If you're having difficulty, search for one on google and copy one off another page.

Now go to settings - general - keyboard. At the bottom is an option to add a shortcut. Paste the radical symbol into the "phrase" section. And put whatever you like in the "shortcut" section. For instance, I put ^^ in under shortcut. Now when i type ^^ on my phone/Ipad it auto corrects to the radical. You could use this method for other math symbols as well.
