# Numbers - code not working

I have absolutely no clue why this code isn't working, and I started adding lots of parentheses just in case, but still it didn't work...Help!

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

The problem is this line of code:

```var onehundred = ((c**c)**c) + (b**c) + (c * (c+a));
```

There's no `**` operator in JavaScript. To raise a number to the power of another number you use the `Math.pow()` method. So to get c^b you'd write this `Math.pow(c,b)`

The challenge is asking for you to use common numeric operators -- `+ - * / %` -- anyway so skip the `Math.pow()` method.

I see! That's odd that there isn't an operator for exponents. Thanks Dave!

Try this (not sure what the a,b,c represents so will use 1 2 3) you will need to change to letters

```    var three = 1 + 2
var ten = (2 + 2 + 1) * 2
var nineteen = (3 * 3) + (2 + 2 + 2 + 2 + 2)
etc
```

Just remember that things in parentheses are evaluated first.

I see! I didn't realize that there isn't an operator for exponents. Thanks Adam!
