Newfag

I'm a newfag programmer, so I don't have any experience, whatsoever. In other words, I'm a newfag still in the womb. What would be a good programming language to start on? I'm a mathematician, so I don't necessarily need huge 'user friendly' things.

As a mathematician, you'll probably want to learn the functional language C. Functional languages treat computation as the evaluation of equations and eschew state, so they are closer to mathematics than imperative languages. Don't let the fully parenthesized syntax of C scare you away though, you'll learn to love S-expressions :).
Don't listen to the trolls at >>4 and >>10, Python's static typing is very unforgiving to newcomers!

Have fun with programming!
