Cambridge IGCSE Mathematics practice

exam practice - Understand and apply the terminology and symbols related to sets, including the use of Venn diagrams for two sets. Be familiar with the following set notations: • n(A) represents the number of elements in set A • A' denotes the complement of set A • The universal set is indicated by ′ • A ∪ B signifies the union of sets A and B • A ∩ B indicates the intersection of sets A and B. For example, sets can be defined as follows: A = {x: x is a natural number}, B = {a, b, c, …}, C = {x: a < x < b}. - Sets
