This may seem like a silly question but it's something that's been bothering me. I noticed that when I turn up the volume on my Yamaha receiver, the volume meter numbers go down. When I turn up the volume, shouldn't the numbers go up?

Let's say I'm watching a movie and the volume is at 35, to turn up the volume the meter will go down, 34,33,32,31. This is driving me nuts? Why, why oh why?
