How to hide the plus (+) and minus (-) symbols in the price

Can someone please explain how I can remove the plus (+) and minus (-) symbols from showing up in the itemized or attribute prices, or at least not showing up in final shopping cart in nopcCommerce 1.9?  

E.g. I would like the attribute or product variant prices to just display like this in the the cart:  $22.00; and not +$22.00 .  

Thanks in advance.

Thanks.  That's it.  I did not understand that after the change one has to recompile.  Much appreciated.
