A set is a collection of things, called elements. These elements may be concrete or abstract (or a mixture) such that, in principle, at least, given any element it is possible to say whether or not it is in the set.
One reason for the "in principle" bit is the set of prime integers. People know what that means: there are clear, simple rules defining prime numbers. But given some huge number it may not be possible to determine if it is a prime.

Kinds of sets are: infinite set-the set continues on for infinity.There may not be an infinite amount of a thing you wear, it is limited to numbers. finite set-it has finite (countable) number of elements, it has unlimited numbers. numerical set-a set having only numbers as its elements, set prime numbers (2,3,5,7,11,13,17..) equal set-two sets are equal if they have precisely the same numbers. null set-its is a set with no elements or numbers. equivalent set-sets with the same numbers of members . intersecting sets-sets with some members in common. subsets-sets contained within others are subset.
