We study the difference-difference Lotka-Volterra equations in
-adic number space and its -adic valuation version. We point out that the structure of the space given by taking the
ultra-discrete limit is the same as that of the -adic valuation space. Since ultra-discrete limit can be regarded as a
classical limit of a quantum object, it implies that a correspondence between classical and quantum objects might be associated with valuation theory.
