Try making a new BBCode:
Title: Math
BBCode Tag Name: Math
Replacement:
Code:
<textarea dir="ltr">{param}</textarea>
Example:
Code:
[math][frc=3]4[/frc]?[frc=1]4[/frc][/math]
Description: Makes things go from left to right, for math equations.
Use {option}: no
Everything else the same..
Should work then if you post something like this..
Code:
[math][frc=3]4[/frc]?[frc=1]4[/frc][/math]
