Welcome to TeX.SX! This is a simple answer, however, you should check the commands and packages specifically for the addition / multiplication / etc. on TeX.SX.
\documentclass{article}
\begin{document}
\[
\begin{array}{rr}
A & B \\
+\ 3 & 7 \\
\hline
9 & A
\end{array}
\]
\end{document}

1In the original question, the $A\ B$ in the first line were right of the other two lines. I suspect (supported by the acceptance) that was not required. +1. Commented Dec 4, 2018 at 4:30

@Raaja: presumably the delimiters you mention are the square brackets. I haven't seen them. What do they do? Commented Dec 4, 2018 at 4:31

@RossMillikan Well, here what I mean by delimeter is that using a \\ instead of a not-so-nice tab space using
&. Commented Dec 4, 2018 at 6:49
I would do:
\documentclass{article}
\begin{document}
\begin{center}\renewcommand{\tabcolsep}{.3ex}\renewcommand{\arraystretch}{.9}
\begin{tabular}{ccc}&$A$&$B$\\ +&$3$&$7$\\ \hline&$9$&$A$
\end{tabular}\end{center}
\end{document}

Another approach with xlop:
\documentclass[12pt]{article}
\usepackage{xlop}
\begin{document}
\oplput(1,2){A}\oplput(2,2){B}
\oplput(0,1.5){$+$}
\oplput(1,1){3}\oplput(2,1){7}
\ophline(0,0.8){4}
\oplput(1,0){9}\oplput(2,0){A}
\end{document}
To show also the solution you only need add some like \vspace{1em}\opadd{59}{37}

1I think
58+37=95is the solution of the addition, not59+37:)– user156344Commented Dec 3, 2018 at 13:23 -
2@DũngVũ With or without taking the last carry? Because then A=5+1 and 59+37 is correct ... Ok, it was just messing, really it was only a typo...
