Excuse me if I am on the wrong StackExchange site. I write about [Physics](https://physics.stackexchange.com/) in [English](https://english.stackexchange.com/) and [typeset](https://graphicdesign.stackexchange.com/) that with [LaTeX](https://tex.stackexchange.com/). So I have a variable _c_, and there are two of them in the same expression. I want to say that the formula looks ill-defined because the same letter represents for two different things. How would I write the plural of the variable _c_? Those are my ideas: [](https://i.stack.imgur.com/4PoYv.png) From the [APA Style blog](http://blog.apastyle.org/apastyle/2011/08/the-grammar-of-mathematics-writing-about-variables.html) I gather that “_c_s” is the way to do it, but I am not sure about this. What is the way to go?
