MATHEMATICAL LANGUAGE AND INFORMAL LOGIC 1.1. A few typographical conventions. Certain kinds of mathematical objects are most often represented by certain kinds of letters. For instance, mathematicians often represent a point by “x” and a function by “f,” and very seldom the other way around...
of many years chemists developed a kind of chemical language — a system of signs and conventions fo rtheir use — which gave them a representation of their fundamental postulate that atoms are the building-blocks of matter; molecules are built up using atoms like the letters of an alphabet....

In ordinary mathematical logic, and I will say what ‘ordinary’ means later in Section 4, we have symbols (letters) for variables: x, y, z, . . . and letters for predicates or properties, such as M and D above. We also have letters for relations and functions. For example, L(x)...

There are a variety of naming conventions depending on the context and field of study, and they are not always consistent. However, in some of the literature you may find variable names to follow a pattern like so:s - italic lowercase letters for scalars (e.g. a number) x - bold ...
