Encyclopedia > Whole number

The whole numbers are the nonnegative integers (0, 1, 2, 3, ...) A negative number is a number that is less than zero, such as −3. ... The integers consist of the positive natural numbers (1, 2, 3, …), their negatives (−1, −2, −3, ...) and the number zero. ...

The set of all whole numbers is represented by the symbol mathbb{W} = {0, 1, 2, 3, ...} In mathematics, a set can be thought of as any collection of distinct things considered as a whole. ...

Algebraically, the elements of mathbb{W} form a commutative monoid under addition (with identity element zero), and under multiplication (with identity element one). Abstract algebra is the field of mathematics that studies algebraic structures, such as groups, rings, fields, modules, vector spaces, and algebras. ... In abstract algebra, a branch of mathematics, a monoid is an algebraic structure with a single, associative binary operation and an identity element. ... In mathematics, an identity element (or neutral element) is a special type of element of a set with respect to a binary operation on that set. ...


Unfortunately, this term is used by various authors to mean:

To remove ambiguity from mathematical terminology, those uses are now discouraged.[citation needed] In common usage positive is sometimes used in affirmation, as a synonym for yes or to express certainty. Look up Positive on Wiktionary, the free dictionary In mathematics, a number is called positive if it is bigger than zero. ... The integers consist of the positive natural numbers (1, 2, 3, …), their negatives (−1, −2, −3, ...) and the number zero. ... The integers consist of the positive natural numbers (1, 2, 3, …), their negatives (−1, −2, −3, ...) and the number zero. ...

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. ...
