I do not understand how this function equals 14, please help!

How does the following function equate to 14? I'm very confused. Could anybody out there explain this to me?

Thanks

  var f = function(a, b){
  var c = a + b;
  return c * 2;
}

  var x = f(3, 4);

yes, down at the bottom you are assigning the integers 3 and 4 to 'a' and 'b'.

You can now look at the second line like it says: var c = 3 + 4;

This is the same as saying: var c = 7;

Then, in the next line, it says: return c * 2;

This is saying: return 7 * 2;

Let me know if that doesn't clear things up and I will try explaining a different way.
