If I want to indicate a negative number in the Equation Editor (Office 2007 and onward), I do this:

```
-5
```

Equation Editor renders it nicely, with the hyphen (minus sign?) right close to the number:

But if I've got something more complicated, like a vector in polar notation:

```
25\angle-5\degree
```

I get this:

Which looks more like "twenty five angle minus five degrees" rather than "negative five degrees".

Is there any way to fix this?
