Built-In Mathematical Calculations
Math is a built-in object with properties and methods for mathematical constants and functions. It is not a function object. Math works with the Number type. Math functions are all static, so each starts with Math.myfunctioncallhere(). Math.PI and Math.random() are two Math functions used a lot when doing calculations.
