\begin{align*}当我尝试使用from进行对齐时出现错误amsmath。
这是我的代码：
\begin{align*}
$[\Gamma(A \otimes B)\Delta, C] &\cong [\Gamma A B \Delta, C]$,\\
$[\Gamma, A/B] &\cong [\Gamma B, A]$, \\
$[\Gamma, A \backslash B] &\cong [\Gamma B, A]$, \\
$[\Gamma, A \times B] &\cong [\Gamma, A] \times [\Gamma, B]$, \\
$[\Gamma(A + B)\Delta, C] &\cong [\Gamma A \Delta C] \times [\Gamma B \Delta, C]$, \\
$[\Gamma I \Delta, C] &\cong [\Gamma \Delta, C]$, \\
$[\Gamma, 1] &\cong \{*\}$, \\
$[\Gamma 0 \Delta, C] &\cong \{*\}$, \\
$[\Gamma, \prod\limits_{x} A(X)] &\cong [\Gamma, A(X)]x$, \\
$[\Gamma \coprod\limits_{x} A(X) \Delta, C] &\cong [\Gamma A(X) \Delta, C]$.
\end{align*}
以下是错误：
Paragraph ended before \align* was complete.
Missing $ inserted.
Missing \endgroup inserted.
Display math should end with $$.

为了澄清起见，我试图使这部分代码（1）在页面中集中，并且（2）在符号中对齐\cong：
像这样：
我该怎么做才能修复我的代码？
答案1
除了 (a) 删除两行全空白行和 (b) 省略所有$符号外，您可能还想 (c) 删除每行末尾看起来繁琐的逗号和 (d) 在最后两行中，使用_{X}而不是_{x}并增加方括号的大小。仍然在最后两行：或者，我会使用\textstyle而不是默认值来调整和符号的\displaystyle大小。\prodcoprod
