Question

What is the best classification of 0 in the real number system?

Answer 1

Answer:

Step-by-step explanation:

The 0 in the real number system goes into the most specific subset of real numbers we have, which is the whole numbers.  Whole numbers include the 0, and next is the less specific natural or counting numbers which do not include the 0. (Next comes the integers and after that rational numbers, each getting less specific as they radiate out from the center)
