Hello Halsey / @SRC-at-SCC ,
I think this is a really neat idea! Are you mostly wondering how to get all of the math notation into the text of your newsletter itself?

If you are using a different software like MathType to write the equations, you could try taking a screenshot and inserting them as images into your newsletter for the most control over the display.
As you mentioned, you could also link to a document or external website that has the equations. Could you use a website like WolframAlpha to link off to the solutions perhaps?
