Set Theory
As per My opinion

Set is a Group. means Collection of Variables, Integer Type Data, Character Type Data.

e.g. 1, 2, ...n, names of Country.

Operations Of Sets:

1.Union:

We Can Consider All the Elements From both Sets .If any elements are same then consider those element only time.

All the elements of Set A and all the elements of Set B with Doing Union operation it is called union operation.

$$A \bigcup B $$

example:

A={1, 2, 3, 4, 5} B={4, 5, 6}

$$A\bigcup B$$={1, 2, 3, 4, 5} $$\bigcup$$4, 5, 6}

={1, 2, 3, 4, 5, 6}

2.Intersection:

We Can Consider only Common Elements From Both sets. All the Elements of Set A and All the Elements Of set B With

Doing Intersection Operation it is called Intersection Operation.

$$A\bigcap B$$

example:

A={1, 2, 3, 4, 5} B={4, 5, 6}

$$A\bigcap B$$={1, 2, 3, 4, 5} $$\bigcap$$ {4, 5, 6}

={4, 5}
