Examples of set in a Sentence Verb We need to set some extra chairs around the table. He set the ladder against the wall and walked away. I remember setting my bag right here. They set the bricks along the walkway. The jeweler can set the stone several different ways. The power set of an infinite either countable or uncountable set is always uncountable. Moreover, the power set of a set is always strictly "bigger" than the original set in the sense that there is no way to pair every element of S with exactly one element of P S.

There is never an onto map or surjection from S onto P S. The cardinality of the empty set is zero. For example, the set of all three-sided squares has zero members and thus is the empty set. Though it may seem trivial, the empty set, like the number zero , is important in mathematics. Indeed, the existence of this set is one of the fundamental concepts of axiomatic set theory.

Some sets have infinite cardinality. The set N of natural numbers , for instance, is infinite. Some infinite cardinalities are greater than others. For instance, the set of real numbers has greater cardinality than the set of natural numbers. However, it can be shown that the cardinality of which is to say, the number of points on a straight line is the same as the cardinality of any segment of that line, of the entire plane , and indeed of any finite-dimensional Euclidean space.

There are some sets or kinds of sets that hold great mathematical importance and are referred to with such regularity that they have acquired special names and notational conventions to identify them. Many of these sets are represented using blackboard bold or bold typeface.

Special sets of numbers include. Each of the above sets of numbers has an infinite number of elements, and each can be considered to be a proper subset of the sets listed below it. The primes are used less frequently than the others outside of number theory and related fields.

Two sets can be "added" together. A new set can also be constructed by determining which members two sets have "in common". Two sets can also be "subtracted". In certain settings all sets under discussion are considered to be subsets of a given universal set U.

An extension of the complement is the symmetric difference , defined for sets A , B as. The power set of any set becomes a Boolean ring with symmetric difference as the addition of the ring with the empty set as neutral element and intersection as the multiplication of the ring.

A new set can be constructed by associating every element of one set with every element of another set. Let A and B be finite sets; then the cardinality of the Cartesian product is the product of the cardinalities:. Set theory is seen as the foundation from which virtually all of mathematics can be derived. For example, structures in abstract algebra , such as groups , fields and rings , are sets closed under one or more operations. One of the main applications of naive set theory is constructing relations.

Given this concept, we are quick to see that the set F of all ordered pairs x , x 2 , where x is real, is quite familiar. It has a domain set R and a codomain set that is also R , because the set of all squares is subset of the set of all real numbers. The reason these two are equivalent is for any given value, y that the function is defined for, its corresponding ordered pair, y , y 2 is a member of the set F.

Although initially naive set theory , which defines a set merely as any well-defined collection, was well accepted, it soon ran into several obstacles.

A set is a well-defined collection of distinct objects. The objects that make up a set (also known as the set's elements or members) can be anything: numbers, people, letters of the alphabet, other sets, and so on. Georg Cantor, one of the founders of set theory, gave the following definition of a set at the beginning of his Beiträge zur Begründung der transfiniten Mengenlehre. Introduction to Sets. Forget everything you know about numbers. In fact, forget you even know what a number is. In sets it does not matter what order the elements are in. Example: {1,2,3,4} is the same set as {3,1,4,2} When we say "order" in sets we mean the size of the set.
