Every real number is either rational, or irrational. Examples of Irrational Numbers include:

* The square root of any positive integer, except that of a perfect square.

* The number pi.

* The number e.

* Any of the above, multiplied by or added to a rational number - for example 2 x pi, 2/3 times the square root of 2, etc.

* An expression like 10 to the power x is irrational for most values of x.
