Question

Are all integers real numbers?

Answer 1

State whether all integers are real numbers or not:

Real numbers include integers, rational, irrational, natural, and whole numbers.

Here are some variations:

In addition to integers, real numbers can also be whole, natural, rational, or irrational. The only positive and negative whole numbers, as well as natural numbers, that are considered to be integers are real numbers.

The set of integer numbers$\left(Z\right)$ is a subset of the set of real numbers$\left(R\right)$.

$Z\subset R$

Every integer number is a real number.

Hence, all integers are real numbers.
