Answer:
The union of two sets is a new set that contains all of the elements that are in at least one of the two sets. The union is written as A∪B or “A or B”. The intersection of two sets is a new set that contains all of the elements that are in both sets. The intersection is written as A∩B or “A and B”.
Example:
*if A1={a,b,c},A2={c,h},A3={a,d}, then ⋃iAi=A1∪A2∪A3={a,b,c,h,d}. We can similarly define the union of infinitely many sets A1∪A2∪A3∪⋯.
* For example, {1,2}∩{2,3}={2} More generally, for sets A1,A2,A3,⋯, their intersection ⋂iAi is defined as the set consisting of the elements that are in all Ai's
