Use set-builder notation to denote the set of all even digits. Let E = set of even digits Textbook answer: E = { x | x is an even digit } = { 0, 2, 4, 6, 8 } Question: Why is 0 an element of set E?

Use set-builder notation to denote the set of all odd digits. Let O = set of odd digits Textbook answer: O = { x | x is an odd digit } = { 1, 3, 5, 7, 9 }. Question Why is 9 on that list of odd numbers when 9 is divisible by 1, 3, and 9?
