Here is MyST.

comparing to RST

This happens in this lecture

@DrDrij it looks like we need floating equation numbers for quantecon-book-theme to support wide equations?
@DrDrij any ideas on this one? Let me know when you might have some time to look at this. Thanks.
@DrDrij I think I will break these equations across two lines.
@mmcky Agreed. It appears most solutions suggest reducing the length of the equation.
Had a fiddle to see what I could do with the HTML that MathJax writes out, but the equation number moves with the equation :/
