The result generally follows directly from the definition. How the proof is stated will depend on how the definition is phrased. For example let's work with the following definitions:
For
-
#x# is less than#y# (denoted#x < y# ) if#x - y = -k# for some positive number#k# . -
#x# is greater than#y# (denoted#x > y# ) if#x - y = k# for some positive number#k# .
Claim: For
Proof:
As each step is reversible, this concludes the proof
