    1. Social Annotation and Mathematics Education

      My internal mathematician wishes there was more substance in this particular portion.

      • Use of \(LaTeX\)
      • annotating the breakdown of logic in problems
      • providing missing context
      • filling in details of problems left as an exercise for the student

    1. **The Cauchy-Schwarz Inequality** $$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$

      This sentence uses $ delimiters to show math inline: $\sqrt{3x-1}+(1+x)^2$

    1. An uncomplicated XML vocabulary for authors of research articles, textbooks, and monographs. The best of DocBook, LaTeX, and HTML. Outputs: print, PDF, web, EPUB, Jupyter Notebooks, … (Before June 2017, PreTeXt was called “MathBook XML”, so many of those references remain.)

      A tool mentioned by Alex Enkerli at I Annotate 2021.

    1. Separating discussion about a page from the page itself is an essential step to free discussion.

      Sounds like separating content from format (à la \(LaTeX\)) and there are interesting parallels between annotations, metadata, and formatting. All of these can be described as “layers”, in the common metaphor.
