Is the set of natural numbers a proper subset of the set of whole numbers?

The set of whole numbers is the set {0, 1, 2, 3, …}. Definition. ... If set A is equivalent to the subset {1, 2, 3, …, N} of the natural numbers, we say that the cardinal number for set A is N. Notation: n(A) = N.

The set of natural numbers is a proper subset of the set of whole numbers, because the number 0 is a whole number, but not a natural number.

Step-by-step explanation:

The natural numbers, referred to using a capital N, are all of the positive whole numbers as well as zero, 0. ... The integers are all of the whole numbers, positive, negative and zero. The natural numbers are a proper subset of the set of integers.
