**Tell us what’s happening:**

**Your code so far**

```js

var a = 3;
var b = 17;
var c = 12;

// Only modify code below this line

a = a + 12;
b = 9 + b;
c = c + 7;

```

What problem are you having? The code you have there has no modification.

“Convert the assignments for `a` , `b` , and `c` to use the `+=` operator.”

Like stated in the challenge having `myVar = myVar + 5;` is the same as having `myVar += 5`, you just have to change `a`, `b` and `c` to `+=`
