Symbol Symbol Name Meaning / definition Example
{ } set a collection of elements A = {3,7,9,14},
B = {9,14,28}
B intersection objects that belong to set A and set B ∩ B = {9,14}
B union objects that belong to set A or set B ∪ B = {3,7,9,14,28}
B subset subset has fewer elements or equal to the set {9,14,28} ⊆{9,14,28}
B proper subset / strict subset subset has fewer elements than the set {9,14} ⊂{9,14,28}
B not subset left set not a subset of right set {9,66} ⊄{9,14,28}
B superset set A has more elements or equal to the set B {9,14,28} ⊇{9,14,28}
B proper superset / strict superset set A has more elements than set B {9,14,28} ⊃{9,14}
B not superset set A is not a superset of set B {9,14,28} ⊅
