What are natural numbers and their examples?
Natural numbers are positive integers, also known as counting numbers. Some examples are 3, 4, 4359.
Why is the set of positive whole numbers closed under subtraction?
The set of positive whole numbers is not closed under subtraction! In order for a set of numbers to be closed under some operation would mean that if you take any two elements of that set and use the operation the resulting "answer" would also be in the original set.26 is a positive whole number.40 is a positive whole number.However 26-40 = -14 which is clearly not a positive whole number. So positive whole numbers are not closed under subtraction.
What are positive and negative whole numbers and zero?
Whole numbers are numbers from 0 to infinity. They must be numbers that are not fractions or decimals, and must be positive. Integers can be any numbers that are whole, negative or positive. Zero is not a positive number. Neither is it negative. Rational numbers are an fraction. Eg: 6/10 or 6/6 They can also be whole numbers because 6/6 is also 1. Counting numbers are also numbers 1-infinity, but once again, it is all whole numbers, meaning that they are not decimals or some thing like: .1 or 1/2
Are negative integers considered whole numbers?
It depends. Some authors consider "Whole Numbers" to be the positive integers, some consider them to be the non-negative integers, and some consider them to be all integers. For the first two definitions, numbers like -3 would not be considered "whole numbers". With the last definition, negative numbers like -3 would be considered a "whole number".
Are rational numbers is a whole number?
Some rational numbers are whole numbers, some are not. The set of whole numbers is a proper subset of rational numbers.
What are some examples of negative and positive integers?
Positive integers are whole numbers greater than 0. In other words 1, 2, 3, ... Negative integers are whole numbers less than zero. Such as -1, -2, -3, ...

Is an integer but not a a whole number?
Some integers are whole numbers, but only 0 through positive infinity. The negatives are not included in the whole numbers.
Is -19 a whole number?
Yes. A whole number is any number (positive or negative) that doesn't have a fraction or decimal. Some examples of whole numbers are 2, -2, 5, 7, 19943.

What is another word for natural number?
Natural numbers are sometimes defined to include zero, sometimes not. Equivalent terms therefore may include: positive integers, non-negative integers, whole numbers, positive whole numbers ("whole number" is ambiguous; some take it to include negative numbers, some not).
What are some examples of Whole Numbers?
Whole numbers refers to numbers that have no decimal or fractional part, such as 0, 1, 2, 3, 4, ... -1, -2, -3, ...

Can some whole numbers be negative?
Yes. A whole number is a number negative or positive from 1 to infinity as long as it is not a fraction or decimal number.
Does a set of whole numbers includes zero but the natural numbers do not?
Actually, the "set of whole numbers" doesn't have a unique definition, so it's better to avoid that term, at least in professional circles. For some people, "whole numbers" means positive numbers (usually including zero), for others, it means "integers" (i.e., both positive and negative whole numbers). The only thing you can be sure about when the term "whole numbers" is used is that it does NOT include fractions or numbers with decimals. The term "natural numbers", on the other hand, was originally used for whole numbers starting with 1; but in recent decades, it has become quite common to include zero. To avoid confusion, you better use terms such as: "Positive integers" (greater or equal to 1) "Non-negative integers" (greater or equal to 0) "Integers" (any whole number, can be zero, positive, negative).
What are examples of integers?
Positive and negative whole numbers: -39, 67, 0, 58, -4 Integers are just negative and positive real numbers and zero. Here is a list: ...... -3, -2, -1, 0, 1, 2, 3, ...... The list continues in both directions.
