Sol. Just enclose inline latex math formulas in [m]mathhere[/m] for Block Maths or [im]mathhere[/im] for Inline Maths.

Input:
[m]\int \frac{x+\sin x}{1+\cos x}[/m]

Output:
\int \frac{x+\sin x}{1+\cos x}

Input:
2^2

Output:
2²

Input:
Can you please help me regarding this [im]\frac{2}{3}[/im]

Output:
Can you please help me regarding this \frac{2}{3}

Input:
[im]\left(1+\frac{1}{x}\right)[/im]

Output:
\left(1+\frac{1}{x}\right)

Our forum supports latex maths equations, If you don’t know how to use latex you can google it.
Don’t forget to enclose inline latex math in [m]mathhere[/m] for Block Maths or [im]mathhere[/im] for Inline Maths.
If you are trying to do superscript or subscript then our forum supports it by default, All you can simply type 2^2 as Input and it will render automatically Output : 2².

If you are trying to superscript or subscript in Latex/MathJax then you have to do like this

Input : 
What's the square of [im]50^{2}[/im]

Output : What’s the square of 50^{2}
This is useful when you are using fractional mathematics:

Input : 
[m]\left(1+\frac{1}{x}\right)^2[/m]

Output:
\left(1+\frac{1}{x}\right)^2
As you can see it won’t rendered

Now enclosing Superscript with {}

Input:
[m]\left(1+\frac{1}{x}\right)^{2}[/m]

Output:
\left(1+\frac{1}{x}\right)^{2}
