This forum does not provide a way to insert LaTeX forumlas to write nicely looking Math equations but we can use an external site called CodeCogs to write some LaTeX and automatically make it compile into an image. Click the LaTeX image at the bottom left on this forum to visit CodeCogs.
Since this forum's background color is darkish and the default background color selection of CodeCogs is transparent we need to change that to white first.
Type your LaTeX using the given templates if you need them.
Now right-click the generated image at the bottom and choose "Copy Image". On BullyWiiHacks inside a message you then just paste (the image).
Result:
If you didn't switch the background color it'll look similar to this which you do not want:
Enjoy
