Can't use $ without it being mistaken for latex.

Cannot use html symbol for $ either, as it gets converted to $, and any backslashes before $ gets removed.

These attempts also didn't work:

• \$
• \\$
• $

If you add the class mathjax_ignore ignore to an element (like a div, or even <markdown></markdown>), latex won't get parsed inside that block, so dollar signs won't cause equations to form.

Example

<div class="mathjax_ignore">
  Mary has $5 to spend. If each apple costs $2 dollars and a banana costs $1 dollar, then how many
  pieces of fruit can Mary get?
</div>
