Is { 0, 20 } closed under multiplication
Are any of these sets closed under multiplication?
To determine if a set is closed under multiplication, we need to check if the product of any two elements from the set is also an element of the same set. For example, the set of integers is closed under multiplication because the product of any two integers is always an integer. In contrast, the set of natural numbers is also closed under multiplication, while the set of rational numbers is closed under multiplication as well. However, sets like the set of positive integers and the set of even integers are also closed under multiplication.
Are negative integers closed under multiplication?

Are polynomial expressions closed under subtraction?

Are rational numbers closed under division multiplication addition or subtraction?
