Title: Fix sign of the result in the circuit diagram

I'm enjoying your article! Here's a minor correction to the circuit diagram, so that it matches your code

```javascript
// initial conditions
var x = -2, y = 5, z = -4;
var q = forwardAddGate(x, y); // q is 3
var f = forwardMultiplyGate(q, z); // output is -12
```
