Question

All numbers positive, negative and 0, that are not irrational

Answer 1

Integers,
`\mathbb Z`

Explanation:

Integers contain the sets of numbers that are positive, negative (including
`0`) and numbers that do not contain a decimal/fractional part, meaning they must be rational numbers. Such numbers are natural numbers, whole numbers and negative whole numbers.

`\mathbb Z` is the symbol that represents all numbers that belong under integers.

Hope this helps :)

Answer 2

Step by step explanation

Irrational numbers are any real numbers that are not rational. So 0 is not an irrational number. Some (in fact most) irrational numbers are not algebraic, that is they are not the roots of polynomials with integer coefficients. These numbers are called transcendental numbers.
