问题与解决方案书

我正在写一本包含问题和解决方案的书。我正在尝试找到获得 pdf 输出的最佳方法，如下所示

第一章 问题集

  1. 问题：等等等等....
  2. 问题：等等....
  3. 问题：等等等等......

第二章：解决方案

  1. 问题 1 的解决方案
  2. 问题 2 的解决方案
  3. 问题 3 的解决方案......

但我想避免手动引用并希望我的代码按照以下方式

\begin{enumerate}
\item Problem 1
\item Solution to problem 1
\item Problem 1
\item Solution to problem 1
\end{enumerate}

是否可以？

答案1

这和你想要的一样吗？

\documentclass{article}
\usepackage{xsim}
\usepackage{blindtext}

\xsimsetup{collect}

\begin{document}

\section*{Set of problems}

\begin{exercise}[ID=A]
  $1+1=$
\end{exercise}
\begin{solution}
  $2$
\end{solution}
\begin{exercise}[ID=B]
  $10\div2=$
\end{exercise}
\begin{solution}
  5
\end{solution}
\begin{exercise}[ID=C]
  Who has a red nosed reindeer?
\end{exercise}
\begin{solution}
  santa
\end{solution}


\section*{Exercises}
\printrandomexercises[collection=all exercises,exclude=D]{3}

\newpage

\printsolutions

\end{document}

您必须运行代码两次才能使练习和解决方案出现在单独的页面上。

这是数学书吗？如果是的话，也许下面的内容更合适。

\documentclass[a4paper]{book}
\usepackage[margin=0.75in]{geometry}
\usepackage{xsim}
\usepackage[english]{babel}
\usepackage{blindtext}


\DeclareExerciseEnvironmentTemplate{number-only}{%
  \par\noindent
  \textbf{\GetExerciseProperty{counter}}%
  \GetExercisePropertyT{subtitle}{ \textit{#1}} %
}{\par}

\newcommand\printsectionexercises{%
  \ForEachUsedExerciseByType{%
    \ifnum\ExercisePropertyGet{##1}{##2}{chapter-   value}=\value{chapter}
    \noindent\ExercisePropertyGet{##1}{##2}{instruction}\par
    \XSIMprint{exercise}{##1}{##2}%
    \fi
  }%
}

\renewcommand\printsolutions{%
  \def\currentchapter{}%
  \def\lastchapter{}%
  \ForEachUsedExerciseByType{%
    \let\lastchapter\currentchapter
    \edef\currentchapter{\ExercisePropertyGet{##1}{##2}{chapter- value}}%
    \ifx\lastchapter\currentchapter\else
    \section*{Chapter \ExercisePropertyGet{##1}{##2}{chapter}}
    \fi
    \XSIMprint{solution}{##1}{##2}%
  }%
}

\DeclareExerciseProperty{instruction}
\newcommand\ExerciseRef[1]{%
  \expanded{%
    \noexpand
    \ExercisePropertyGet{exercise}{\GetExerciseIdForProperty{ID}{#1}}.   {counter-value}%
  }%
}
\newcommand\This{\GetExerciseProperty{counter-value}}

\xsimsetup{
  exercise/template = number-only ,
  solution/template = number-only ,
  exercise/within = section ,
  exercise/the-counter = \arabic{exercise}. ,
  exercise/print = false
}

\begin{document}

\chapter{ChapterOne}
\section{Solving for an unknown}
\blindtext

\begin{exercise}[instruction={In Exercises \This--    \ExerciseRef{last:x}, solve for \(x\).}]
  \(x - 1 = 0\)
\end{exercise}
\begin{solution}
  \(x = 1\)
\end{solution}
\begin{exercise}
  \(3x - 12 = 0\)
\end{exercise}
\begin{solution}
  \(x = 4\)
\end{solution}
\begin{exercise}[ID=last:x]
  \(x^2 - 3x + 2 = 0\)
\end{exercise}
\begin{solution}
  \(x = 1, 2\)
\end{solution}

\begin{exercise}[instruction={In Exercises \This--    \ExerciseRef{last:y}, solve for \(y\).}]
  \(y^3 - 6 y^2 + 11 y - 6 = 0\)
\end{exercise}
\begin{solution}
  \(y = 1, 2, 3\)
\end{solution}

\begin{exercise}[ID=last:y]
  \(y^4 - 10 y^3 + 35 y^2 - 50 y + 24 = 0\)
\end{exercise}
\begin{solution}
  \(y = 1, 2, 3, 4\)
\end{solution}

\subsection*{Exercises}
\printsectionexercises

\newpage

\chapter*{Solutions to the exercises}
\printsolutions

\end{document}

这就是你想要的东西吗？
