Whole numbers are the positive naturals; I've generally seen N0 as a notation for the natural numbers without zero - that is, the whole numbers. Log in to post comments By goodmath on 23 Jan 2007 ...

The natural and whole numbers are usually considered to be exact (e.g. there are 4 tires on a car, 8 legs on a spider). But sometimes they are approximate (e.g. there were 1000 people in the crowd). Here are the whole numbers, shown on the number line: The Integers Now ...

The set of natural numbers is denoted as $$\mathbb{N}$$; so: $$$\mathbb{N}=\{1,2,3,4,5,6\ldots\}$$$ Natural numbers are characterized by two properties: The number 1 is the first natural number and each natural number is formed by adding 1 to the previous one. When we subtract or divide two natural numbers the result is not necessarily a ...

The chart helps us recognize that certain numbers can fall into several categories. For example, take the number 3. Three is a real number, a rational number, an integer, a whole number, and a natural number. The opposite of 3 or -3 is also real, rational, and an integer, but it is not whole or natural.

I was always taught that natural numbers are positive integers. Whole numbers start at zero and integers include negative numbers. Antonio Adrian says: 2 Apr 2018 at 11:29 pm [Comment permalink] Any natural number will follow this: A>B A-B is smaller than A. Except for 0: A>0 A-0 equals to A. Dr. Cocktor says:

$\mathbb{N}$ = natural numbers ($\mathbb{Z^+}$) = {$1, 2, 3, \ldots$} Even though there appears to be some confusion as to exactly What are the "whole numbers"?, my question is what is the symbol to represent the set $0, 1, 2, \ldots $. I have not seen $\mathbb{W}$ used so wondering if there is another symbol for this set, or if this set does ...
