Need help with JavaScript program

[steVENOM]

Hi! I'm in need of some help with my JavaScript work for programming. I need to make a program that adds 2 parameters together as a function and returns them. The problem I'm having is that its a function and I'm still learning how to properly execute functions. Here is the question being asked by my instructor followed by my current progress.

 

Question: *in the image*

My answer: 

//add function - adds two numbers together

var add = function( operand1, operand2) {

  var sum = (operand1 + operand2);
return sum;
 

}

//Now add two test cases that will call the add function with different parameters.

add(10,10);

Have you tried running the code?
