Sum multiple Rasters

Hey folks,

silly question here, but I can't seem to find an easy answer.  I'm using Arc 10.0...

I have several rasters that are a series of floating point values (several hundred thousand points) where each point is an elevation change over a period of time (i.e. raster1=timeA-timeB, raster2=timeB-timeC, etc...).  Each raster has the same extent, and same number of points (in the same locations). 

I want to sum these rasters together (i.e. rastersum=timeA-timeD).  I can use the "Plus" feature in Spatial Analyst, but that only allows you to add two rasters at a time.  Even doing a batch process with Plus is a multi-step process...

Is there a simpler way (i.e. non-python) that allows me to do this?  I'm assuming there is, but I haven't stumbled upon it yet. 

Thanks!
