Check in File -> preferences and check the use negative values option. Be forewarned, puting neg values into everything doesnt always work.

what the hell did u just said...?

He means go to the file menu in World Editor, choose Preferences. In Preferences there's an option called "Use Negative Values." Turn it ON. Good luck.

Alternatively you can just hold Shift when double clicking a field you want to edit in the Object Editor. If you do that then it allows negative values without setting it to in preferences. Plus shift-clicking can be used to edit certain fields in ways you couldnt normally, such as lightnings.
