Every positive number x is the product of two normal numbers.

The number "x" is a big and variable number, something over 20.

This means learning about equations and how to solve them (for example, "find a number x where ").

A root is a number x so that .

For example, take the statement "There exists a number x such that it is not y".

Suppose we need to square a number x near 50.

If it is I, then generate a random number x in (0,1).

It is not hard to show that any real number x can be expanded in this way.

Every real number x is either less than 1/2 or not; and likewise so is the fractional part of 2x.

These rules apply for any real or complex number x, unless otherwise stated.
