What does it mean when we say polynomials are closed under multiplication?

Polynomials are closed under subtraction. When multiplying polynomials, the variables’ exponents are added, according to the rules of exponents. The whole numbers are closed under addition, which guarantees that the new exponents will be whole numbers. Consequently, polynomials are closed under multiplication.
