math on the iPad?

Hi, I was wondering if it is possible to do math on the iPad? I see the option to have equations read out in nemeth braille in the braille settings, but haven't had any luck either finding equations, or writing them out. I'm wondering if this is possible? If so, how would I go about doing so?
Any suggestions or advice would be greatly appreciated.
Thanks, Matthew


There's a calculator app

there's a calculator app that comes with a standard and scientific calculator. In portrait mode, it's standard, and in landscape, it scientific.


Thanks, but that wasn't really my goal. I'm interested in using the iPad to complete math assignments, unfortunately I need to write equations down for this. I'm just trying to find a good electronic way to do so. I would prefer braille if possible, but...
