ℕ-numbers are numbers that count. By that I mean, numbers such as, 1, 2, 3, etc. (You may also know ℕ-numbers, as whole numbers.) ℤ-numbers, also known as integers, are like ℕ-numbers, but include, the negatives. According to the definitions I have given you, we are able to say that, question one is true.
