General ⇒ Formatting a page with many small math problems

[Xiphias]

Hello!

Sorry if this topic already has been covered and I could not find it.

I am currently making a math problem compendium for a lower level high school class. It consists of many smaller problems and I am having some issues in making it look good in terms of spacing and lining up problems without having to manually space out every single line.

Here is a part of my code:

Code: Select all

\documentclass[14pt,norsk,a4paper,twoside]{memoir}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{babel,graphicx,varioref}
\DeclareSymbolFont{letters}{OML}{ztmcm}{m}{it}
\DeclareSymbolFontAlphabet{\mathrm}{letters}
\title{Oppgaver 2P}
\begin{document}

\maketitle

\chapter{Potenser og tall på standardform}
\section{Negative tall}
\subsection{Addisjon} Regn ut \\
\textbf{1.10 a)} $2+(-1) $ \: \: \: \textbf{b)} $2-3 $ \: \: \: \textbf{c)} $1-3 $ \: \: \: \textbf{d)} $-3+4 $ \: \: \: \textbf{e)} $-5+2 $ \: \: \: \textbf{f)} $-1-4 $ \\

\noindent \textbf{1.11 a)} $-2+3-2 $ \: \: \: \textbf{b)} $5-1-2 $ \: \: \: \textbf{c)} $3-4-1 $ \: \: \: \textbf{d)} $-5+1-5 $ \: \: \: \textbf{e)} $3+2-1-3 $ \: \: \: \textbf{f)} $-3+(-1)-2+5 $ \\

\subsection{Multiplikasjon} Regn ut \\
\noindent \textbf{1.12 a)} $3\cdot(-2) $ \: \: \: \textbf{b)} $(-2)\cdot 2 $ \: \: \: \textbf{c)} $(-4)\cdot (-2) $ \: \: \: \textbf{d)} $(-3)\cdot 2\cdot (-1) $ \: \: \: \textbf{e)} $3\cdot 1 \cdot (-1) $ \: \: \: \textbf{f)} $(-1)\cdot (-2) \cdot (-3)$

\end{document}

How could this be organized to look better and also be less work? Would having an entire set of problems in math mode and allign it somehow be better?

Thanks in advance

Welcome, you are dealing with LaTeX, manually adjusting stuff is seldomly needed. There shouldn't be any real work for this kind of document.

Have a look at the example below, using dedicated packages, you can easily do what you want. Using chapters might be a bit overkill here, personally i would probably go one level lower.

Code: Select all

\documentclass[14pt,norsk,a4paper,twoside,article]{memoir}
\usepackage{libertine}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{babel,graphicx,varioref}
\usepackage{libertine}
\usepackage{exsheets}
\SetupExSheets{headings-format={\normalsize\sffamily}}
%\DeclareTranslation{Norsk}{exsheets-exercise-name}{}
\usepackage{tasks}
\settasks{label-format={\sffamily}}
\DeclareSymbolFont{letters}{OML}{ztmcm}{m}{it}
\DeclareSymbolFontAlphabet{\mathrm}{letters}
\title{Oppgaver 2P}
\begin{document}
\chapter{math stuff}

\subsection{Addisjon} Regn ut% \\%Don't do that

\begin{question}
\begin{tasks}(4)
\task  $2+(-1) $ 
\task $2-3 $
\task $1-3 $ 
\task $-3+4 $
\task $-5+2 $ 
\task $-1-4 $ 
\end{tasks}
\end{question}

\begin{question}{6}
\begin{tasks}(3)
\task $-2+3-2 $ 
\task $5-1-2 $ 
\task $3-4-1+1-1+1-1+1-1 $ 
\task $-5+1-5 $ 
\task $3+2-1-3 $ 
\task $-3+(-1)-2+5 $
%\\%Don't do that
\end{tasks}
\end{question}

\setcounter{question}{23}%just for demonstration
\subsection{Multiplikasjon} Regn ut% \\%Argh
\begin{question}
\begin{tasks}
\task $3\cdot(-2) $ 
\task $(-2)\cdot 2 $ 
\task $(-4)\cdot (-2) $
\task $(-3)\cdot 2\cdot (-1) $ 
\task $3\cdot 1 \cdot (-1) $ 
\task $(-1)\cdot (-2) \cdot (-3)$
\end{tasks}
\end{question}

\end{document}

Perfect! This is exactly what I needed. Thank you so much! Had no idea there was a task environment.

I use chapters because the memoir environment has sections start at "0.1"

[Johannes_B]

Memoir is primarily used for reports and books, but you can use global option article to get into article-mmode.

[Xiphias]

I used memoir to get bigger font size by default. This is also probably possible in article environment, but I did not know how.

[Xiphias]

A small follow up question. Is it possible to have questions be numbered with "1.1 , 1.2 ..." instead of "1, 2, 3 ..."?

[Stefan Kottwitz]

Sure, with

Code: Select all

\usepackage{amsmath}

which should be used for math in any case, and

Code: Select all

\numberwithin{question}{section}

or the same with chapter or any sectioning.

Stefan

[Xiphias]

Hmmm, that is having an effect. I did \numberwithin{question}{section} which reset the counter per section. But it did not change the numbering of questions from "1, 2, 3,..." to "1.1, 1.2, 1.3..." It just started as "1, 2, 3..." for the next section.

[Stefan Kottwitz]

Ok, then you may also need

Code: Select all

\renewcommand*{\thequestion}{\thesection.\arabic{question}}

Stefan

[Xiphias]

I don't want to be naggy, but that did not do anything it seems.
