Intersection AND

Union AND, MOSTLY

Disjunction OR

Conjunction AND

For these words, we have:

Intersection, when we and the common results between two sets

So, Intersection A ∩ B A and B

A ={1,2,3} B= {3,4,5} A ∩ B ={3}

Disjunction, OR

When some conditions apply either to one set or to another.

A V B = OR

He is American OR He is British

A OR B

Union, AND, Mostly

When we want all the elements that belong to both Sets

So A ∪ B means A and all the elements from A and all the elements from B, no need no repeat the same element.

A = {1,2,3} B= {3,4,5} A ∪ B ={ 1,2,3,4,5}

Conjunction

A ^ B = AND,

In Logic and Set Theory and we have conjunction, we can use the word

He is a New Yorker AND He is American.
