Mathjax não está funcionando

[AnkitJain (Vihaani)]

I tried to get a fraction with this code:

$$\frac{a}{b}$$

It gives the above text itself. I checked plugin is enabled.

Try with just a single dollar sign on each side:

$\frac{a}{b}$

[AnkitJain (Vihaani)]

Worked

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

[david (David Taylor)]

\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}

@AnkitJain

$$\frac{a}{b}$$

So i needed to put double dollars in seperate lines. Thanks for the explanation.

@david

$$
\frac{a}{b}
$$

Worked!

My double dollars were on the same line. So it was not working?
