Thought Shower

As revision for my Prolog class test on Friday I wrote a small program that works as a (very) simple calculator. %A simple calculator %By D. Duncombe add([],0). add([H|Tail],Total) :- add(Tail,Total2), Total is Total2 + H. mult([],1). mult([H|Tail],Total) :- mult(Tail,Total2), Total is Total2 * H.

So if you need to multiply 17 numbers of over 100 digits, I'm your man.

Right, well, for starters no animals use radar (except humans of course) so I'm guessing he meant echo-location. He also mentioned Barn Owls, so we'll rule them out. Let the searching begin! 'echo location in animals...
