I would like to notify that this notation:
x^2 - 5x + 6
does not work in SimPy, as it gives the following error:
{"error": "Sympify of expression 'could not parse 'x^2 - 5x + 6'' failed, because of exception being raised:\nSyntaxError: invalid syntax (, line 1)"}
This is because '^' is identified as the XOR operator. In SimPy, exponentiation is identified with ' ** '.

You should write that in your readme, because even if Claude can correct the equation as necessary, it still wastes a try by giving the wrong notation in the question, and therefore wastes tokens.

Thank you for pointing this out. I didn’t get a notification earlier and just saw your comment today. You’re absolutely right and I’ll update the README to make this clear.
I also encourage others to comment or open issues directly on GitHub.
