Hello, I like to study via flash cards and have down loaded apps such as mental case, however, much of the material I like to study rely on equations. I find that most flash card apps don't conveniently support typing fractions, special greek symbols or exponents. Does any one know if there is way I could write out equations on iPad and use them on flash card apps? I do own Noteshelf, Evernote and Noterize but I haven't figured out a way to write out an equation on them, save it as a jpg and then transfer it over to mental case. This sounds like a lot of steps anyways. Any advice would be appreciated.
