I tried to get a fraction with this code: $$\frac{a}{b}$$ It gives the above text itself. I checked plugin is enabled.

\frac{a}{b} will render the expression inline, which can be quite small, especially for fractions. To render larger expressions, use the block format \frac{a}{b} More examples can be found here: [图片] Discourse Math Plugin discourse2 Summary Discourse Math …

Try with just a single dollar sign on each side: $\frac{a}{b}$

Worked 1_Font size become too small. But RIGHT CLICK on the equation gave SETTINGS options to select size and other options

[图片] AnkitJain: $$\frac{a}{b}$$ So i needed to put double dollars in seperate lines. Thanks for the explanation.

[图片] david: $$ \frac{a}{b} $$ Worked! My double dollars were on the same line. So it was not working?

\frac{a}{b} 将以行内方式渲染表达式，这可能会显得相当小，尤其是对于分数。若要渲染更大的表达式，请使用块级格式

\frac{a}{b}
