Raster Extents + Calculator Problems

I'm using ArcGIS 10 and attempting to use raster calculator to sum the values between two raster datasets. 

However, the extent of of one of the rasters is much smaller than the other, so the output extent is only ever the smaller extent. How do I increase the extent of the smaller raster so that the output is consistent with the entire/larger raster?

I've tried changing the processing extents in the environment options, but that doesn't work either.

Thank you,
