Question:
are there any "standard" ways of indicating the meaning of numerical values in formulas, resp. general mathematical texts (theorems, proofs, etc.)?
I am especially looking for suggestions to tell apart the weight of a graph's edge from a multiplicity of that weight.
Background is that I want to demonstrate, how to calculate a sufficiently high constant that, when added or assigned to certain edge's weights, does some "tricks" e.g., ensuring that some specific edges are included in the output of a tsp solver.
As an example, consider the case where I have e.g. 5 edges, each of weight $1$ and I want to demonstrate via some calculations how I reach a result, but want to allow for a clear distinction between the cardinal 5 and the scalar weight $1$. Is it in that case customary to use different fonts like $5*\mathbf{1}$ or rather to put the cardinals to one side of the multiplication sign and the weight on the other?
I am aware that what is considered "good" or "best" is largely in the eye of the beholder, so this question is aimed at an overview of notations.
Some background on the origin and/or articles in which a specific notation is used would be great.
