What is Polynomial?
Adding and subtracting polynomials means combining like terms — matching powers. Multiplying means distributing every term of one across every term of the other, then collecting.
How it works
Each polynomial is parsed into coefficients by power, the selected operation is applied term by term, and the result is printed in standard descending order with zero terms dropped and its degree reported.
