According to Wikipedia: In mathematics, a natural number is either a positive integer (1, 2, 3, 4, ...) or a non-negative integer (0, 1, 2, 3, 4, ...). The former definition is generally used in number theory, while the latter is preferred in set theory and computer science.

Natural Number. A natural number is an integer greater than 0. Natural numbers begin at 1 and increment to infinity: 1, 2, 3, 4, 5, etc. Natural numbers are also called "counting numbers" because they are used for counting. ... In computer science, natural numbers are commonly used when incrementing values.

From this definition, we can intuitively say that the set of natural numbers is bounded below by any number . However, we note that is not bounded above since such as does not exist. Therefore in general we say that the set of natural numbers is not bounded.

No, an imaginary number is not positive or negative. A positive number is greater than zero, and a negative number is less than zero; but “greater than” and “less than” don't exist for Complex numbers, only for Real Numbers, and Imaginary numbers are always Complex numbers.

Main types ): The counting numbers {1, 2, 3, ...} are commonly called natural numbers; however, other definitions include 0, so that the non-negative integers {0, 1, 2, 3, ...} are also called natural numbers. Natural numbers including 0 are also called whole numbers.
