Set Theory Part 1 Set Theory Introduction Youtube We introduce the basics of set theory and do some practice problems.this video is an updated version of the original video released over two years ago. hopef. A set is the mathematical model for a collection of different things; a set contains elements or members, which can be mathematical objects of any kind: numb.

Sets and set theory — discrete structures for computing. 2.1. sets and set theory. most of mathematics is built up from the very basic concept of a set. it is so basic in fact, that the concept of a set is rarely defined formally rather something thought of intuitively as just “a collection of objects”. defining sets formally is outside. A = the set of all even numbers. b = {2, 4, 6} c = {2, 3, 4, 6} here b ⊂ a since every element of b is also an even number, so is an element of a. more formally, we could say b ⊂ a since if x ∈ b, then x ∈ a. it is also true that b ⊂ c. c is not a subset of a, since c contains an element, 3, that is not contained in a. Theorem 1.1.1. two sets a and b are equal if and only if a ⊂ b and b ⊂ a. if a ⊂ b and a does not equal b, we say that a is a proper subset of b, and write a ⊊ b. the set is called the empty set. this set clearly has no elements. using theorem 1.1.1, it is easy to show that all sets with no elements are equal.
