raster algebra:  Manipulations and functions that operate on raster objects cell by cell.  Any raster object can be used as a variable, or operand, in a raster algebraic expression.  You just set up a combination of operands in an equation and then assign a raster object to each operand.  The result of the operation is stored in a new raster object.
