Problem with extra [MATH] [/MATH] signs

[Math Amateur]

In a post on Group algebras on the Linear and Absract Algebra forum I am having some troubles with Latex.

One of the problems is that the editor seems to automatically put in extra $$ $$ sign when I hit save changes or submit.

The line in question is

$$ = \alpha_{g_1} g_1 +\alpha_{g_2} g_2 + \ … \ … \ + $$$$\alpha_{g_n} g_n $$

Even when I clear the extra signs the code does not work?

Another line I am having similar trouble with is as follows:

$$ = \beta_{h_1} h_1 + \beta_{h_2} h_2 + \ … \ … \ + \beta_{h_n} h_n $$

Can anyone see why this is not displaying correctly?

$$ = \alpha_{g_1} g_1 +\alpha_{g_2} g_2 + \ … \ … \ + \alpha_{g_n} g_n$$$$ = \beta_{h_1} h_1 + \beta_{h_2} h_2 + \ … \ … \ + \beta_{h_n} h_n $$

I stripped all the COLOR tags that were embedded in the code. I suspect you use the WYSIWYG editor and perhaps were unaware that you had these BBCodes embedded in your code.

Hi Mark,

I am just visiting a friend in Melbourne in the state of Victoria and am working with my friends Mac instead of my PC which I have left in Tasmania.

Problem must be with the Mac somehow

The one at the upper left. If that button has a white background, then you are using the WYSIWYG editor. Click that button to change to standard mode, and then you will see the raw code of your post, and you can then edit out the COLOR tags.

Oh my goodness … yes, colour tags everywhere … thank you Mark … will edit them out ...

Thanks for the help … much appreciated
