Multiple Grid Statistics

Option on  Raster GIS, Multiple grid arithmetic,  submenu.

Takes you to Grid tab of Options form which lets you pick the grids to create and how to handle missing data.

Grids you can create, using all the open grids

A missing point in one grid can invalidate the result at a pixel, which will also be missing, or if the program can do statistics with those grids which have a value.

The resulting files will have the extent of the active map when you select the option, and will have the same resolution.
