I have a web site that shows its content it two direction. rtl & ltr.

When page is in ltr content mode, every thins is OK and the negative sign shows in the left of number.

```
body {
    direction: ltr;
}

```

But when page is in rtl mode, 

```
body {
    direction: rtl;
}

```

the negative sign of numbers shows in the right of number.

Whereas I want to show negative sign in the left of number in both cases. How do I do this?
Thanks.
