我是 Latex 的初学者，我想知道如何枚举案例。我尝试使用\begin{case}，但编号不对。如果我有多个涉及案例的问题，编号不会在每个问题之后重新开始，而是继续，就像什么都没发生一样。我该如何停止这种情况。此外，当我谈论案例时，我指的是案例 1 和案例 2
我还使用了在 sharelatex 上找到的所有这些包：
\documentclass[28pt]{article}
\usepackage{fancyhdr}
\usepackage[includeheadfoot,margin=1.0cm]{geometry}
\usepackage{amsmath,amsthm,amssymb}
\usepackage{enumitem}
\usepackage{mathtools}
\usepackage{framed}
\usepackage{chessfss} %chess figure for HW #2
\usepackage[english]{babel} %table for problem A.43
\usepackage{multirow} %table for problem A.43 %\usepackage[table]{xcolor} color certain blocks in a table %\usepackage[pass,showframe]{geometry} just to show the margins \usepackage[makeroom]{cancel} \usepackage{array} %BETWEEN TWO 2-DIGIT NUMBERS
