An ordered relation, or a directed relation is the generic building block of Partially ordered sets[1]. It can be visualized as an arrow that relates two objects with an explicit direction. The directionality of a directed relation breaks the symmetry of symbolic representation, which is the smallest amount of information, therefore, directed relations can be used to represent any other kinds of information contentCite error: Invalid <ref> tag; invalid names, e.g. too many. Ordered relations are particularly useful in representing causal relations[2].
Prefix and Postfix Expressions
Since order matters, the sequence of how certain symbols appears in an expression also matters a lot. There are two kinds of expressions:
