What is R * in math?

In a different context, the notation R* denotes the reflexive-transitive closure of a (binary) relation R in a set X, i.e. the smallest relation in X that contains R and is reflexive as well as transitive. It is the union of all the non-negative powers of R, where R^0 = ∆_X, the diagonal relation in X and R^n =R•R•….

Are numbers natural?

A natural number is an integer greater than 0. Natural numbers begin at 1 and increment to infinity: 1, 2, 3, 4, 5, etc. Natural numbers are also called “counting numbers” because they are used for counting. For example, if you are timing something in seconds, you would use natural numbers (usually starting with 1).
