Complement of a Set Examples. To make it more clear consider a universal set U of all natural numbers less than or equal to 20. Let the set A which is a subset of U be defined as the set which consists of all the prime numbers. Thus we can see that A = { {2, 3, 5, 7, 11, 13, 17, 19} }Boolean Functions: Consider the Boolean algebra (B, ∨,∧,',0,1).

15.1: Cyclic Groups. Groups are classified according to their size and structure. A group's structure is revealed by a study of its subgroups and other properties (e.g., whether it is abelian) that might give an overview of it. Cyclic groups have the simplest structure of all groups.

A digital device is an electronic device which uses discrete, numerable data and processes for all its operations. The alternative type of device is analog, which uses continuous data and processes for any operations.

And you can see from the definition f (x) = (x,5-x) that the function takes a single value and produces an ordered pair of values. So is the domain here all numbers? No, all integers. Z is the standard symbol used for the set of integers.
