我正在尝试使用嵌套枚举块来获取按字母顺序排列的列表，当嵌套块不在引用块中时，它会抛出错误（！LaTeX 错误：出现问题 - 可能缺少 \item）。我想删除引用块，这样列表就不会缩进太多。非常感谢任何帮助，谢谢。

\begin{enumerate}
\begin{enumerate}
\item $1 + 2 + 3 + 4 + 5 + 6 +\cdots+ 10=\boxed{\sum_{i=1}^{10}i}$
\item $ 2 + 4 + 6 + 8 +\cdots+2n=\boxed{\sum_{i=1}^{n}2i}$

%BLOCK 3
%Copy the following block of text for each problem in the assignment.
\textbf{Exercise 0.3:} Factorial review: What is the factorial function? What notation is used for this function?
\\ A factorial function uses the notation $``x!"$ and is equivalent to $\prod_{i=0}^{x-1}(x-i)$.
