Inline latex not rendering

I’ve been making educational posts on my github.io page related to programming and statistics. In previous posts I have had no issue with using latex, whether it is inline or $$display$$. However, in a new post, the inline latex will not render. Is anyone able to help me?

edit: I realized my mistake after checking previous posts. It’s been a while, and apparently the inline also require $$inline$$ to render properly. Sorry for the trouble!
