I need to write + operator for polynomials. How can I do that for
(that's an example, i need for all polynomials!:)) expression (3x^2 +
2x + 2) + (2x^2 + 2x +5)

Well, first start with defining the class that represents your polynomials
...
(with proper tests, on "input" and "output" methods).

When that is done, start defining the '==', '+', '*', ... methods
(with proper tests, otherwise you wouldn't pass if I was your professor)

Doing the polynomial division and "find poles" would be fun to
earn better grades :slight_smile:

HTH,
