This link http://d2l.ai/chapter_preliminaries/linear-algebra.html contains MathML/Mathjax is not converted properly. MathML/MathJax expressions are not accurate after the conversion. Everything else seem to be good except the MathML expressions. Please fix it.
Thanks for the report. I’m afraid Push to Kindle doesn’t support these at the moment. We’d like to add support in the future though.
