Actually this is technically right (according to LaTeX markup). If you want to get rid of the numbering, then use align*, as in

\begin{align*}
(a+b)^3 &= (a+b)^2(a+b)\\
&=(a^2+2ab+b^2)(a+b)\\
&=(a^3+2a^2b+ab^2)+(a^2b+2ab^2+b^3)\\
&=a^3+3a^2b+3ab^2+b^3
\end{align*}

which gives:

strangely... well i was trying to get it numbered... Tested on another TEX editor and it works as it should. check it yourself: http://www.numberempire.com/texequationeditor/equationeditor.php

I see your problem. Interestingly numberempire are using an older version of our system - so we've somehow introduce a bug!

We'll look into this. Thanks for posting the correct image.
