Is -4 a natural number an integer or both?
It is only an integer, as natural numbers are all integers from 0 (e.g. 0, 1, 2, 3, 4…). According to another definition of the set of natural numbers, integers from 1 are considered natural. In other words, according to the first definition, the set of natural numbers is all non-negative integers. According to the second definition, the set of natural numbers is all positive integers.
-7 is a prime number?
No it is not. By definition, a prime number must be a natural number. Negative numbers are not in the set of natural numbers.
Why 0 not be considered as natural number?
Depending on the definition of the words "natural numbers", the natural numbers are either, "the set of positive integers", that is, integers from 1 upwards, or "the set of non-negative integers", that is, integers from 0 upwards.Therefore, 0 can be included as one of the natural numbers, depending on your definition.
What is the only whole number that is not a natural or counting number?
Zero, by the traditional definition of natural numbers.
Why The set of whole numbers include zero but the natural numbers do not?
The Dedekind-Peano axioms form the basis for the axiomatic system of numbers. According to the first axiom, zero is a natural number. That suggests that the question refers to some alternative, non-standard definition of natural numbers.
Can a number be both natural and positive?
The most common definition of 'natural' numbers is: The counting numbers.According to that definition, all natural numbers are positive.
What you called natural numbers with 0?
I would call them "natural numbers". The natural numbers are normally assumed to include zero; although that was not part of the original definition.

What is the only whole number that is not a natural or counting number?
Zero, by the traditional definition of natural numbers.
What is a natural numbers greater than on that have no other factors except one and themselves?
That is the definition of prime numbers.

What is a set of natural numbers and zero?
The set of natural numbers plus zero is the set of all non-negative integers. Please note that the definition for the set of natural numbers is ambiguous. Some definitions include zero, while others exclude it.
Are All rationals numbers are in the set of natural numbers?
1. No.The Natural numbers are the positive integers (sometimes the non-negative integers).Rational numbers are numbers that can be expressed as the quotient of two integers (positive or negative). All Natural numbers are in the set of Rational numbers. 2. No. Natural numbers are usually defined as integers greater than zero. A Rational number is then defined simply as a number that can be expressed as an integer divided by a natural number. (This definition includes all rational numbers, but excludes division by zero.)
How do the whole numbers differ from the natural numbers?
Natural numbers, according to the strictness of the definition, can refer to all positive numbers, that is, 1, 2, 3, 4, 5.... or all non-negative numbers, that is, 0, 1, 2, 3, 4, 5... (note the inclusion of the number 0 in this list). Whole numbers can include negative whole numbers, for example, -1, -2, -3, -4, -5, numbers you do not find in the list of natural numbers.
Is one natural number divided by another natural number always a natural number?
No, 4/3 is 1.333333... which is not a natural number. However, any natural number divided by a natural number will always be a rational number. This is due to the definition of a rational number as being able to be expressed as p/q where p and q are integers. Thus, numbers where p and q are natural numbers represent a subset of all the rational numbers.
