JavaScript JavaScript Foundations Numbers Operators

Why is var ten not equal to 10?

I am not sure why this code isn't going through... Any thoughts?

    <link rel="stylesheet" href="core.css">
    <script>
      var a = 1,
          b = 2,
          c = 4,
          three = c-a,
          ten = c*b + b;




      /* 
      Common operators used in numeric calculations:
            addition: +
         subtraction: -
      multiplication: *
            division: /
             modulus: %
            grouping: ()

      Your tasks in this code challenge will consist of
      creating variables and assigning correct values to
      them using only variables a, b, and c and the above
      operators. For example, if the task is "Create a
      variable named "seven" and assign the correct
      numeric value 7 to it using only variables a, b,
      and c and the common numeric operators." then one
      possible solution would be:
      var seven = a + b + c;
      Another solution could be:
      var seven = (b * c) - a;
      Or:
      var seven = a + a + a + a + a + a + a;
      But that's kinda lame. Good luck! */

You have to call it in order to see the result.

Try console.log(ten) or alert(ten).

Your code is correct for var ten to be equal to 10, the problem seems to be with how treehouse evaluates your answer. Try assigning 'three' and 'ten' individually:

  var a = 1,
      b = 2,
      c = 4;
  var three = c-a;
  var ten = c*b + b;

The above worked for me.

Thanks, Michael, this worked!
