How do I number equations in Latex?

Answer 1

The following code will automatically assign a number to the equation between the begin and end statements.

\begin{equation}
E = mc^2
\end{equation}

This will display:
E = mc² (1)

Answer 3

if you're using standard installation this environment should work:

\begin{equation}
%%% here type your equation: NO dollar or whatever delimeters%%%
\label{eqn:%%%here type equation name%%%}
\end{equation}

latex will automatically number your equation according to sections and is roman by default.

the label is when you have to cite the equation for which you use (\ref{eqn:%%%the equation name you're citing%%%})

the parenthesis above is for aesthetics only since "cite" only gives you a number, e.g. 5 and not what almost everybody would expect: (5)

hope that helps

I dont know... but when I look for latex's math code, I go to wikipedia math pages that contain images that contain the symbol Im looking for... and hit the edit link... I check out the code they have embedded and use it.
