# Set Theory - Intersection, Union, Difference, Sort

A calculator for the set theory. Two sets of numbers can be intersected, joined, subtracted and sorted. The elements will be counted and multiples will be deleted. Please enter any amount of numbers for Set A and Set B. Comma and point will be interpreted as decimal separator. As separators between numbers, space, break and semicolon can be used. Other characters, except for numerals, are not allowed.

**Correct set x**: converts every element from set A or B into a number, sorts those and deletes multiples. The result will be written into the input field.

**Intersection**: and-operation, calculates the intersection of set A and B and corrects it. If an element was in set A and in set B before, then it will be in the result set.

**Union**: -operation-operation, calculates the joining of set A and B and corrects it. If an element was in set A or in set B or in both before, then it will be in the result set.

**Difference x-y**: takes all the elements from one set and removes those that also occur in the other set.

**XOR**: exclusive or, takes only those values which are in one set, but not in both.

**Example**: presets some simple values for set A and B. With those, the calculation operations can be performed.
