文档中不需要右缩进

我是超级菜鸟，所以请原谅任何错误！:)

我的问题是，在我的文档中（见下例），从第二个标记开始的段落会自动缩进。我不想这样；我希望所有左边缘都完美对齐。如何做到这一点？

\documentclass{article}
\usepackage{amsmath}
\usepackage{pifont} %For the very nice dingbats

\begin{document}

\section*{Elementary Algebra}

\ding{234} One amusing way to look at \textbf{irrational numbers} is to say that they don't behave rationally. The point is, given their non-terminating, non-repeating decimals, there's no `sane' way to work with them!

\ding{234} Here are some elementary but easily forgotten (and highly useful) algebraic identities:

\begin{itemize}

    \item $a^3 - b^3 = (a-b)(a^2+ab+b^2)$

\end{itemize}

\end{document}

在每个 \ding{234} 之前添加\noindent（第一个除外：那样没用），或者\parindent=0pt在序言中设置 - 但随后您应该将其固定\parskip为非零值（比如说\smallskipamount）以区分段落。

您还可以将这些段落视为（第一级）项目环境中的项目，加载 enumitem包并写入：

    \documentclass{article}
    \usepackage{amsmath}
    \usepackage{enumitem}
    \usepackage{pifont} %For the very nice dingbats

    \begin{document}

    \section*{Elementary Algebra}
    \begin{itemize}[label = \ding{234},wide, labelindent = 0pt]

    \item One amusing way to look at \textbf{irrational numbers} is to say that they don't behave rationally. The point is, given their non-terminating, non-repeating decimals, there's no `sane' way to work with them!

    \item Here are some elementary but easily forgotten (and highly useful) algebraic identities:

    \begin{itemize}[label = \textbullet, align = left,  labelindent = 1.5em, labelsep* = 0.5em,labelwidth = 1em,  leftmargin =! ,topsep = 0pt]
        \item $a^3 - b^3 = (a-b)(a^2+ab+b^2)$ 
        \item $a^3  +  b^3 = (a + b)(a^2-ab+b^2)$
    \end{itemize}

    \end{itemize}

    \end{document}
