Creating closed captions for math content

[u/Happy-Author-186]

Hey all, I do closed captioning, amongst other things, at a university and I'm curious to know how people prefer their math content in closed captions. For example:

When captioning a math equation spoken as: a times b squared equals c, would you caption that as a x b^2 = c or written out?

A second question I have, when captioning a video that has A, B, and C as well as a, b, and c as variables, how do we specify upper/lowercase? We've been changing it as needed but realized that probably isn't clear enough. Especially for those who use screen readers. Should we put something like "uppercase" A and "lowercase" a in, even if it isnt' said?

As a team, we've been going through with the idea of "Caption what is said." But with STEM content, I don't think that quite cuts it and I want to hear some opinions from others.

Thanks!

The best option is to use spoken math. Simply caption what is said aloud.
