A JavaScript Math object provides no. of properties and methods for performing mathematical operations. Math is not a constructor and all the properties and methods of Math are static.
Example:
<script>
var num = Math.random();
var squarRoot = Math.sqrt(num ) ;
document.write("Random Number: " + num + "</br>");
document.write("Square root: " + squarRoot );
</script>
