A . set. is an unordered collection of objects, called . elements. of the set. A set is said to . contain. its elements. If S and T are sets, and (x S) ->(x T) then we say that S is a . subset. CMPS 2433- Chapter 2. Partially borrowed from Florida State . University and . Dr.. R Halverson. Introduction. A . set. is a collection of objects. The order of the elements does not matter. Objects in a set are called . 1/12/16. Section 2.1: Sets. What is a mathematical set?. How can the idea of cardinality be used to describe numbers?. How can sets be used to develop inequalities?. Today We’ll Discuss. How would you explain to a young student what a “number” is???. By the end of class you will be able to use set vocabulary to answer questions about sets.. Five Words….Three Words. Activator. Vocabulary. Set: A Collection of objects, known as elements or members.. Sec 2-1 . Lecture on Intro to Sets . A . set. is a collection of objects.. MATH 110 . Sec 2-1 . Lecture on Intro to Sets . A . set. is a collection of objects.. For example: . the set of seasons . S. Use set notation and terminology.. List elements of a finite set.. Describe the rule that defines a set.. Describe and recognise equality of sets.. Perform intersection, union.. Investigate commutativity for intersection and union.. A set is an object defined as a collection of other distinct objects, known as elements of the set. The elements of a set can be anything: people, plants, numbers, functions, and even other sets.. Using sets, nearly any mathematical concept can be derived. A set is a well defined collection of objects. A collection of beanie babies. A collection of hats. An . Element (∈. ) is one of the objects in a set. A = {1, 2, 3}. 1 ∈ A. 2 ∈ A. 3 ∈ A. 4 ∉ A. Set Notation. Objectives. Develop an understanding of set operations. Set Notation. From the ways in which you select clothes in your closet to how you organize the apps on your smartphone, the use of sets allows us to have a systematic way to analyze groups of items and information.. itemsets. : alternative representations and combinatorial problems.
