You don't like "my" proof because its conclusion follows so readily from
the definition? All proofs follow from definitions. Do you think a
proof of one step is less good than one of many steps? Why?

Here's the definition:

x + 0 = x
x + y' = (x + y)'

' being successor. No set theory required.

So what? I might have 0^0 = 5.214.
