Urutkan menggunakan paket multicol

Question

Saya mengerjakan satu set soal untuk siswa dan saya ingin merinci daftar mereka secara horizontal. Namun ketika saya mencoba melakukan itu salah satu item muncul sedikit di atas item lainnya dan konten item sedikit di bawah.

Saya melampirkan MWE dan hasil yang sesuai. Bantuan apa pun akan sangat dihargai.

        \begin{enumerate}[label=(\alph*)]
            \item $\left|\begin{matrix} 3 & 0 \\ 2 & 6 \end{matrix}\right|$

Answer 1

Inilah solusi yang tidak menggunakan multicolslingkungan. Sebaliknya, ia memuat enumitempaket dengan opsi inlinedan menggunakan enumerate*lingkungan. Solusinya juga menggunakan mesin amsthmpaket untuk merampingkan definisi problemlingkungan.

\documentclass[12pt]{article}
%% (I've simplified the preamble code to the bare minimum)
\usepackage{amsmath,amssymb,amsthm}
\theoremstyle{definition} % upright-lettering style
\newtheorem{problem}{Problem}

\usepackage[inline]{enumitem} % <-- note the option 'inline'

\begin{document}

\setcounter{problem}{6} % adjust as needed
\begin{problem}
Calculate the following determinants.

\begin{enumerate*}[label=(\alph*)]
\item $\begin{vmatrix} 3 & 0 \\ 2 & 6 \end{vmatrix}$ 
\hspace*{1cm} %  choose a suitable amount of horizontal whitespace
\item $\begin{vmatrix} a & a \\ b & b \end{vmatrix}$ 
\hspace*{1cm}
\item $\begin{vmatrix} a+b & a-b \\ a-b & a+b \end{vmatrix}$ 
\hspace*{1cm}
\item $\begin{vmatrix} 3^t & 2^t \\ 3^{t-1} & 2^{t-1} \end{vmatrix}$
\end{enumerate*}
\end{problem}

\end{document}

Answer 2

Solusi cepat lainnya adalah:

1. untuk menggunakan \usepackage[margin=1in]{geometry};
2. enumitemsebaris \usepackage[inline]{enumitem};
3. Untuk menulis matriks dengan benar \begin{vmatrix}....\end{vmatrix};

Anda juga bisa menggunakan paket Adjustbox .

\documentclass{article}
\usepackage{amsmath,amssymb,amsthm,adjustbox}
\usepackage{multicol}
\begin{document}
With top alignment
\begin{multicols}{3}
    \begin{enumerate}
        \item\adjustbox{valign=t}{$\begin{vmatrix}a & b \\c & d\end{vmatrix}$}
        \item\adjustbox{valign=t}{$\begin{vmatrix}a & b \\c & d\end{vmatrix}$}
        \item\adjustbox{valign=t}{$\begin{vmatrix}a & b \\c & d\end{vmatrix}$}
    \end{enumerate}
\end{multicols}
With middle alignment
\begin{multicols}{3}
\begin{enumerate}
        \item\adjustbox{valign=m}{$\begin{vmatrix}a & b \\c & d\end{vmatrix}$}
        \item\adjustbox{valign=m}{$\begin{vmatrix}a & b \\c & d\end{vmatrix}$}
        \item\adjustbox{valign=m}{$\begin{vmatrix}a & b \\c & d\end{vmatrix}$}
    \end{enumerate}
\end{multicols}
\end{document}
