VSarkiss was just trying to rewrite what you wrote more cleanly. But do a search for Ackermann's function and you consistently come up with the function as I wrote it.

Incidentally as noted in this biography, what Ackermann actually came up with was a function of 3 variables. This was later simplified by Rosza Peter then Raphael Robinson into the current textbook form which I wrote.
