Can not seem to figure it out, why it is not adding to 100?

Why is this not adding to 100 = 64+32+2+2 = 100 or not?

      var a = 1,
          b = 2,
          c = 4;
      var three = a+b;
      var ten = c+c+b;
      var nineteen = (c*c)+ c - a;
      var onehundred = (c*c*c)+ (C*b*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! */

Hello Muhammad,

It looks like the issue is the use of an undeclared variable capital C instead of your lower-case c variable on the following line.

var onehundred = (c*c*c)+ (C*b*C) +b+b;

Try changing them to your lower-case variable.

I hope this helps.

You used Capital C in one line of code it should be all lower case letting in your line of code to get the result of 100

Cheers! Stephen

cant make it for 100 if I put like this 

var three = a + b;
      var ten = b + b * c;
      var nineteen = c * c + b + a;
      var onehundred = ten * ten;
