What does AUB )' mean in math?
The union of A and B, written AUB, is the set of all elements that belong to either A or B or both.
How do you read apostrophe math?
It's often read as "f-dashed". The punctuation mark, by the way, is not an apostrophe. It is always a straight line, whereas in many fonts an apostrophe is curved.
What are the symbols in sets?
Mathematics Set Theory Symbols
| Symbol | Symbol Name | Meaning |
|---|---|---|
| set | a collection of elements | |
| A ∪ B | union | Elements that belong to set A or set B |
| A ∩ B | intersection | Elements that belong to both the sets, A and B |
| A ⊆ B | subset | subset has few or all elements equal to the set |
What does ∩ mean in sets?
The intersection of two given sets is the set that contains all the elements that are common to both sets. The symbol for the intersection of sets is "∩''. For any two sets A and B, the intersection, A ∩ B (read as A intersection B) lists all the elements that are present in both sets, the common elements of A and B.
