Symbol | Symbol Name | Meaning / definition | Example |
---|---|---|---|

{ } | set | a collection of elements | A = {3,7,9,14}, B = {9,14,28} |

A ∩ B | intersection | objects that belong to set A and set B | A ∩ B = {9,14} |

A ∪ B | union | objects that belong to set A or set B | A ∪ B = {3,7,9,14,28} |

A ⊆ B | subset | subset has fewer elements or equal to the set | {9,14,28} ⊆{9,14,28} |

A ⊂ B | proper subset / strict subset | subset has fewer elements than the set | {9,14} ⊂{9,14,28} |

A ⊄ B | not subset | left set not a subset of right set | {9,66} ⊄{9,14,28} |

A ⊇ B | superset | set A has more elements or equal to the set B | {9,14,28} ⊇{9,14,28} |

A ⊃ B | proper superset / strict superset | set A has more elements than set B | {9,14,28} ⊃{9,14} |

A ⊅ B | not superset | set A is not a superset of set B | {9,14,28} ⊅ |
