MAYBE

Problem:
 minus(x,x) -> 0()
 minus(0(),x) -> 0()
 minus(x,0()) -> x
 minus(s(x),s(y)) -> minus(x,y)
 le(0(),y) -> true()
 le(s(x),0()) -> false()
 le(s(x),s(y)) -> le(x,y)
 quot(x,y) -> if_quot(minus(x,y),y,le(y,0()),le(y,x))
 if_quot(x,y,true(),z) -> divByZeroError()
 if_quot(x,y,false(),true()) -> s(quot(x,y))
 if_quot(x,y,false(),false()) -> 0()
