Subtraction and division are not monoid operations. As such, they do
not have an associated identity value.
They also choose to handle the single argument case specially: (- x)
is equivalent to (- 0 x) and (/ x) is equivalent to (/ 1 x).
Making (/) return the multiplicative identity would be consistent though.
