笔记中怎么在单行内打出latex公式How to type latex formulas within a single line in notes

在复制网页内容时，我发现在笔记的单行内出现了latex公式，但不知道怎么才能手动输入
While copying the content of the page, I noticed that the latex formula appeared within a
single line of the notes, but I don't know how I can enter it manually

Surround inline math with $ (e.g., $2+2$) or type $$ followed by a space to create a block.
