math is "The indispensable or intrinsic properties that characterize or identify something" I think math consist of law,equation,theorem,axiom,some rule.but where does computation come to play? I even suspect computation is not part of math. what is computation? add substract multiply division roundding is computaton. but what is the procedure of those? forexample:32+53=85 what math theory does it base? what make 32+53 to 85? I can not say more, just tell me where does computation come to play?
