do resolution changes effectively average data ?

[National Centre]

Hello,

	In grass, if you have a 10 metre grid resolution raster data layer and
you go from 10 metre resolotion to 100 metre resolution using g.region, and then
perform an operation on that raster data layer; -  does the opertion occur on an
averaged value from all original 10 metre grid cells in order to produce the new
100 metre grid raster - or does the operation occur only on the top left 10
metre grid cell value within the new 100 metre grid? Or does something else
happen?

	Cheers, Al.
