Just a beta of what I was working on lately. It evaluates mathematical expressions like 2*3. Anyways, its explained in the program. Report of any bugs would be great because I haven't tested it out that much. Without further ado, you can download the program here, here or here.
Try the last one first, it has less ads, hopefully. Thanks for helping.

No code?

Sorry I don't release code. Although, I can post small snippets if anyone wants to ask something.
