No. Natural numbers may or may not include 0, depending on who you ask (i.e. they can begin 0, 1, 2, 3, … or 1, 2, 3, 4, …), but they don't ever include the negative numbers. However, integers, which are a superset of the natural numbers (i.e. the natural numbers are contained "in" the integers), do include negatives.
even, whole, non-negative numbers. (zero is not a natural number)
No, -7.3 is not a natural number. Natural numbers are whole numbers greater than zero, so they cannot be negative or contain decimals. The set of natural numbers is typically denoted as {1, 2, 3, ...}. Negative numbers and decimals fall under different categories, such as integers and real numbers, respectively.
Negative numbers are not natural, but there are negative integers. Examples are -1,-2,-3,-4, and so on. These are all integers but none of them is a natural number.
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.)
Zero is a member of the set of whole numbers. Some people include it in the set of natural numbers, some people don't.
No. Negative integers are whole numbers but not natural.
No. Negative whole numbers are not natural numbers.
No. Natural numbers are a subset of whole numbers. Negative numbers are whole numbers but not natural.
The numbers 1,2,3,... etc are called natural numbers or counting numbers. Integers are the natural numbers plus zero plus the negative ( or opposite ) natural numbers. Why do we need negative natural numbers ? For one thing x + 1 = 0 is an equation whose solution is x = -1. We could not solve this equation if we did not have negative integers. So over history these negative numbers came about as a way to solve certain math problems. The numbers 1,2,3,... etc are called natural numbers or counting numbers.

No. The natural numbers are positive.
No. For two reasons: 1) Negative numbers are not natural numbers 2) All natural numbers are rational numbers but the square root of 6 is an irrational number and thus cannot be a natural number.

No, Negative Nine or -9 is not a natural number since natural numbers mean only those numbers which start from 1 to infinity. No negative integers are included in this category of numerals.
