Writing your own structural directives with context variables

Complete code in math.directive.ts

After reading this you will be able to create a structural directive with inputs and context variables and use it like this:

<div *math="10; exponent: 3; let input; 
            let exponent = exponent; let r = root;
 let p = power; let ctrl = controller"&gt;
