In what mathematics? Even for unsigned integers (a, b) the result of
the subtraction operator *must* be a signed integer and the inequality
still holds. Now you can't promote the signed result of the
subtraction to an unsigned value without major lossage, but that's a
whole different problem.

Lisp in many ways, albeit Lisp as channeled by an awk script on acid.
