beamer
I have the following in my document:
\documentclass{beamer}
\usepackage{xcolor}
\setbeamertemplate{footline}[frame number]
\usetheme{Goettingen}
\useinnertheme{circles}
\beamertemplatenavigationsymbolsempty
\setbeamertemplate{footline}[frame number]
\begin{document}
\frame{
\frametitle{test}
test
}
\end{document}
How can I make these frame numbers bigger?
Only one ; at the end is required. The errors come from the unpaired {} for each child. That is, every child must have a beginng { and an ending }. Also proper indentation would help in debugging. Actually, the use of underscore is not a problem here because it is a style name.
Here 3 cases are demonstrated because you have defined 3 levels.
Code
\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{arrows}
\tikzset{
treenode/.style = {align=center, inner sep=0pt, text centered,
font=\sffamily},
arn_n/.style = {treenode, circle,black, draw=black, text width=1.3em},%
level distance = 2.5cm,
level 1/.style={sibling distance=5.75cm},
level 2/.style={sibling distance=1.95cm},
level 3/.style={sibling distance=0.6cm}
}
\begin{document}
\begin{frame}
\frametitle{Paragraphs of Text}
$\bf{Step 0 }$\\
\begin{tikzpicture}[scale=0.5]
\node [arn_n] {0}
child{ node [arn_n] {1}
child{node [arn_n] {2}}
child{node [arn_n] {2}}
child{node [arn_n] {2}}
child{node [arn_n] {2}}};
\end{tikzpicture}
\begin{tikzpicture}[scale=0.5]
\node [arn_n] {0}
child{node [arn_n] {1}}
child{node [arn_n] {1}
child{node [arn_n] {2}}
child{node [arn_n] {2}}
child{node [arn_n] {2}}};
\end{tikzpicture}
\begin{tikzpicture}[scale=0.5]
\node [arn_n] {0}
child{node [arn_n] {1}}
child{node [arn_n] {1}
child{node [arn_n] {2}}
child{node [arn_n] {2}
child{node [arn_n]{3}}}};
\end{tikzpicture}
\end{frame}
\end{document}
You do need to tell beamer what you want to appear in each frame of the handout version. You can use \onslide specifications to do this so that you do not need to modify the existing overlay specifications at all. (I'm not sure this is what you want - probably not.)
The following code modifies your MWE so that, in presentation mode, there would actually be 10 slides within the frame. These are then placed on slides 1 or 2 of the handout. This is a waste of code: if you only want to show slide 5 and slide 10, you do not need two \againframe but only one. But, anyway, with the two:
\documentclass[handout]{beamer}
\begin{document}
\begin{frame}<1-| handout:0>[label=foo]{My only frame}
\begin{enumerate}[<+->]% or whatever you like for presentation mode
\onslide<1-| handout:1-2>
\item Item \arabic{enumi}
\item Item \arabic{enumi}
\item Item \arabic{enumi}
\item Item \arabic{enumi}
\item Item \arabic{enumi}
\onslide<1-| handout:2>
\item Item \arabic{enumi}
\item Item \arabic{enumi}
\item Item \arabic{enumi}
\item Item \arabic{enumi}
\item Item \arabic{enumi}
\end{enumerate}
\end{frame}
\againframe<0| handout:1>{foo}
\againframe<0| handout:2>{foo}
\end{document}
More efficiently with only one repeat:
\documentclass[handout]{beamer}
\begin{document}
\begin{frame}<1-| handout:1>[label=foo]{My only frame}
\begin{enumerate}[<+->]% or whatever you like for presentation mode
\onslide<1-| handout:1-2>
\item Item \arabic{enumi}
\item Item \arabic{enumi}
\item Item \arabic{enumi}
\item Item \arabic{enumi}
\item Item \arabic{enumi}
\onslide<1-| handout:2>
\item Item \arabic{enumi}
\item Item \arabic{enumi}
\item Item \arabic{enumi}
\item Item \arabic{enumi}
\item Item \arabic{enumi}
\end{enumerate}
\end{frame}
\againframe<0| handout:2>{foo}
\end{document}
I'm not sure how this could apply to article mode since then there are no frames or slides.

You can set the
page number in head/footfont; a little example usingsize=\large:
