The discussion centers around the challenge of preventing line breaks in mathematical expressions when posting in a forum. Users express a desire for a way to "glue" text together, such as using tags around expressions to maintain their integrity. While LaTeX is an option, there is concern that it may not be server-friendly. A workaround suggested is to eliminate spaces in the expressions, but this approach has limitations as some symbols still cause breaks. There is a consensus that starting a new line for lengthy expressions is a practical solution, although some participants express frustration with posts that stretch the layout, particularly on smaller screens. Overall, the conversation highlights the balance between readability and formatting in online discussions.
