Simple add function returns NaN

This is my code:

var i=5;
var j=5;

function sum(n,m){
  var num = n + m ;
  alert(num);

};

sum(i+j);

When I run it, it should return '10', but it returns NaN.

Please help me with what I'm doing wrong.

I figured what I was doing wrong.

this below code works - 

var i=5;
var j=5;

function sum(n,m){
  var num = n + m ;
  alert(num);

};

sum(i, j);

Change it from sum(i + j) to sum(i, j). So technically your code was passing originally like sum(10, undefined) which resolved as NaN.

var i=5;
var j=5;

function sum(n,m){
  var num = n + m ;
  alert(num);

};

sum(i, j);

I hope that helps!
