Let us see the different types of symbols used in Mathematics set theory with its meaning and examples. George Cantor created this theory who was born in Russia on March 3, 1845. To refresh, the union of sets is all elements from all sets. To indicate that an object x is a member of a set A one writes x ∊ A, while x ∉ A indicates that x is not a member of A. Set Theory formulas will very helpful to understand the concept and questions of the chapter Set Theory. Set Theory Formulas. However, none of the objects of the set can be the set itself. Rate Us. 1. – cardinality of set A. Set Theory Formulas: The set that contains all the elements of a given collection is called the universal set and is represented by the symbol ‘µ’, pronounced as ‘mu’. Mathematics Set Theory Symbols. Set Theory: Formulas & Examples with Basics Georg Cantor – the founder of set theory “Set Theory” is a branch of mathematics that studies sets, which made up with the collection of distinct and well-defined objects called elements or members of that particular set. Active 5 years, 3 months ago. Example:-In 6000 people 3500 people read English news paper 2500 people read Hindi and 800 people read both news paper then how many people does not read news paper? In naive set theory, a set is a collection of objects (called members or elements) that is regarded as being a single object. 9. For example A = {1, 3, 9, 7} and B = {3, 1, 7, 9} are equal sets. A set is described by listing elements separated by commas, or by a characterizing property of its elements, within braces { }. Click here to learn the concepts, problems & solutions of Set Theory & Venn Diagrams through the study notes. Definition 1. – Intersection of set A and set B. 2. 1. If A and P are overlapping set, \(n( A\cup P ) = n(A) +n(P) – n (A\cap P) \) If A and B are disjoint set, \(n(A\cup B) = n(A) +n(B)\) For a group of two sets: Union of Associativity Sets: A∪ (B∪C) = (A∪B)∪C.
