数学书：练习 - 解决方案环境

如果我使用 Sebastian 的问题公式提供的代码用于运动环境。

\usepackage{lipsum}

\newtcolorbox[auto counter]{problem}[2][]{%

我们如何创建解决方案环境，以便我们在书的末尾提供练习的解决方案，其中每个练习都有章节，页面，练习数量以及相应的难度级别？

答案1

我建议您阅读exercise包文档。

有以下套餐选项：

lastexercise如果答案没有给出参考文献，那么答案应该参考最后的练习（见第 2.1 节）。

和

answerdelayed保存答案，而不是排版。稍后可以使用命令将答案包含在文档中\shipoutAnswer。

和Exercise环境选项：

difficulty练习的难度（数字）。稍后将通过计数器显示\ExerciseDifficulty。

您可以从这个简单示例开始，然后进行自定义。如您所见，如果您Answer在相应的后面立即写下您的环境Exercise，则答案会自动加入到上一个练习中。

\documentclass[11pt]{book}
\usepackage[lastexercise,answerdelayed]{exercise}

\usepackage{lipsum}

\begin{document}

    \chapter{Test 1}

    \lipsum[1]

    \section{Problems}

    \begin{Exercise}[difficulty={1}]
        My easy exercise.
    \end{Exercise}
    \begin{Answer}
        My answer to my easy exercise.
    \end{Answer}

    \chapter{Test 2}

    \lipsum[1]

    \section{Problems}
    \begin{Exercise}[difficulty={2}]
        My difficult exercise.

这是针对问题 - 解决方案环境的 MWE，它结合了@Sebastiano 代码和@CarLaTeX 代码数学书：如何写练习和答案

然而，正如我们所见，这是一个相当笨拙的解决方案。在我看来，最实用的方法是立即为问题和相应的解决方案建立统一的环境。比如

\begin{prob}
\lipsum[2]
\begin{solution}
.....
\end{solution}
\end{prob}

因此，此解决方案（如果存在）将自动发送到包含练习解决方案的章节。不幸的是，我没有足够的 LaTeX 经验和知识来做到这一点。
