synopsis: "[
The specification implies command line input stream and also
implies a range for both `A' and `B' (e.g. (-1000 <= A,B <= +1000)).
To test in Eiffel Studio workbench, one can set Execution Parameters
of "2 2", where the expected output is 4. One may also create other
test Execution Parameters where the inputs are out-of-bounds and
confirm the failure.
