You should put your symbol format definitions in another TeX file; publications tend to have their own styles, and some may use bold Roman for fields like R instead of blackboard bold. You can swap nams.tex with aom.tex. I know, this is more common with LaTeX, but the principle still applies. For example: A natural number can be used to express the size of a finite set; more precisely, a cardinal number is a measure for the size of a set, which is even suitable for infinite sets. This concept of "size" relies on maps between sets, such that two sets have the same size, exactly if there exists a bijection between them.The ∀ (for all) symbol is used in math to describe a variable in an expression. Typically, the symbol is used in an expression like this: ∀x ∈ R. In plain language, this expression means for all x in the set of real numbers. Then, this expression is usually followed by another statement that should be able to be proven true or false.The natural numbers are often represented as equally spaced points on a number line, as shown in the figure, increasing forever in the direction of the arrow. The sum or product of two natural numbers is also a natural number. For example, Sum: 2 + 3 = 5 2 + 3 = 5.
