Hi Dhamnekar,

Do you mind clarifying your use case, what is a specific example of what you would like to write?

One can write chemical equation directly in post body, e.g.:

2 KMnO

How to get Ion like S 2-. The 2- in exponent.

Attachment of PDF is it possible?

We enabled attachemeneta and added support latex, formula and equation:

H

2 KMnO

\(\frac{\partial f}{\partial x} = 2\,\sqrt{a}\,x\)

Code: Select all

`[formula]H2SO4[/formula]`

_{2}SO_{4}📖Code: Select all

`[equation] 2 KMnO4 + 16 HCl = 2 KCl + 2 MnCl2 + 8 H2O + 5 Cl2[/equation]`

_{4}+ 16 HCl = 2 KCl + 2 MnCl_{2}+ 8 H_{2}O + 5 Cl_{2}📖Code: Select all

```
[latex]\frac{\partial f}{\partial x} = 2\,\sqrt{a}\,x[/latex]
```

Great, but it needs some explanation of the syntax how to do.

Latex math syntax:

Ions are also supported now, example:
Ca

Ions are also supported now, example:

Code: Select all

`[equation]Ca{2+} + SO4{2-} = CaSO4[/equation]`

^{2+}+ SO_{4}^{2-}= CaSO_{4}📖
