Document Classes ⇒ aligning formulas in displaymath

[gates]

Hei

I want to align formulas in math mode to left. By defult it aligns formulas in center.

Code: Select all

1
\begin{displaymath}(3+5i)\cdot(30-i)=90-3i+150i-5i^2=-5i^2+147i+90\end{displaymath}

Also I woluld like to create a list (enumerate) of formulas so, that there the formula is in the same line as list number. How can i accomplish this? Right now it is like:

Code: Select all

Code, edit and compile here:

1

\begin{enumerate}
\item \begin{displaymath}(3+5i)+(-5-4i)=-2+i\end{displaymath}
\item \begin{displaymath}(3+5i)-(-5-4i)=8+9i\end{displaymath}
\end{enumerate}

And how can I input Slavic (Russian) letters?

Hi,
for 1. and 2.: use the fleqn class option. For 3., use the babel and inputenc packages. Depending on your distribution, you'll perhaps need to install language support or hyphenation pattern.
Here is an example:

\begin{document}
\begin{displaymath}(3+5i)\cdot(30-i)=90-3i+150i-5i^2=-5i^2+147i+90\end{displaymath}
\begin{enumerate}
\item \begin{displaymath}(3+5i)+(-5-4i)=-2+i\end{displaymath}
\item \begin{displaymath}(3+5i)-(-5-4i)=8+9i\end{displaymath}
\end{enumerate}

This uses UTF-8, but other input encodings are probably also supported.

Concerning the list of formulas, you can simply enter math in inline mode:

Code: Select all

Code, edit and compile here:

1

\begin{enumerate}
\item $(3+5i)+(-5-4i)=-2+i$
\item $(3+5i)-(-5-4i)=8+9i$
\end{enumerate}

I need to type only a few characters in russian. What exatly should I add and how do I type those characters? I can see, my latex .txt file is in iso 8859-1.

With my formula problem I desided to stay with inline mode. And thanks for those links/pdf!
