I'll give it a try:
Iterative functions f_{n}, f_{n+1}, f_{n+2} ... can be described by f_{n+1}=g[f_{n}] where g represents a function.

Given x + y = z
Then:
[tex]z_n = \frac{\left[ x *10^{n1} \right] + \left[ y * 10^{n1} \right]}{10^{n1}} [/tex]
And the limit:
[tex]\lim_{n \rightarrow \infty} z_n = z[/tex]
You can 'evaluate' edition this way, it doesn't make much sense to do so but it is a way of show addition can be described as an iterative procedure for [itex]x, y, z \in \mathbb{R}[/itex] in terms of adding numbers of integers, which themselves can be expressed as iterative procedures.
