I am writing a program that when given an image of a low level math problem (e.g. 98*13) should be able to output the answer. The numbers would be black, and the background white. Not a captcha, just an image of a math problem.

The math problems would only have two numbers and one operator, and that operator would only be +, -, *, or /.

Obviously, I know how to do the calculating ;) I'm just not sure how to go about getting the text from the image.

A free library would be ideal... although If I have to write the code myself I could probably manage.
