TeX - LaTeX Asked on September 2, 2021
I am having the issue with the alignment of an array.
Please, find the below code:
documentclass[12 pt, a4paper]{book}
usepackage{multicol}
usepackage{geometry}
geometry{
a4paper,
total={170 mm,257 mm},
left=20 mm,
top=20 mm,
}
usepackage{amsmath,bm}
usepackage{amsfonts}
usepackage{amssymb}
usepackage{soul}
usepackage{indentfirst}
usepackage[utf8]{inputenc}
usepackage{palatino}
usepackage[dvipsnames]{xcolor}
usepackage{graphicx}
usepackage{fancyhdr}
usepackage{array}
usepackage{enumitem}
usepackage{mathtools}
usepackage{cancel}
usepackage{arydshln}
setlength{parindent}{2em}
newcommand{wt}[2]{underset{substack{textstyleuparrowhidewidthmathstrut#2hidewidth}}{#1}}
definecolor{mygray}{gray}{0.6}
begin{document}
textbf{Solution :}
[
left.
hspace{1 cm}
begin{array}{cccccc}
& & 1 & 0 & 1 & 0
times & & & 1 & 0 & 1
hline
& underline{1} & 1 & 0 & 1 & 0
& 0 & 0 & 0 & 0 &
1 & 0 & 1 & 0 & &
hline
1 & 1 & 0 & 0 & 1 & 0
end{array}
right. hspace{0.25 cm}vline hspace{0.1 cm} text{parbox[t]{13 cm}{As, the product of binary multiplication would always be less than 2. It won't generate any carry.}}
begin{array}{ccccccccc}
& & textbf{Product/Sum} & & textbf{Base} & & textbf{Carry} & & textbf{Result}
1 + 0 + 1 & = & 2 > 1 & = & 2 & times & 1 & + & 0 [0.2 cm]
end{array}
]
end{document}
The obtained output of this is as follows:
As, one can see in the image the second array is aligned to the right of the text. I want that array below the text.
The desired output is as follows:
Can anyone help me to solve this issue?
Probably not too elegant since I used nested tabulars to position math elements, texts and lines.

In order not to guess about the width of the material on the right side, you can use tabularx
and nest array
and tabular
in it.
documentclass{article}
usepackage{geometry}
usepackage{amsmath,bm}
usepackage{tabularx,array}
usepackage{arydshln}
geometry{
a4paper,
total={170 mm,257 mm},
left=20 mm,
top=20 mm,
}
begin{document}
noindenttextbf{Solution:}
[
begin{tabularx}{textwidth}{@{} c | X @{}}
$begin{array}{cccccc}
& & 1 & 0 & 1 & 0
times & & & 1 & 0 & 1
hline
& underline{1} & 1 & 0 & 1 & 0
& 0 & 0 & 0 & 0 &
1 & 0 & 1 & 0 & &
hline
1 & 1 & 0 & 0 & 1 & 0
end{array}$ &
begin{tabular}{@{}p{linewidth}@{}}
As the product of binary multiplication would always be less than~$2$,
it won't generate any carry.

[begin{array}{ccccccccc}
& & textbf{Product/Sum} & & textbf{Base} & & textbf{Carry} & & textbf{Result}
1 + 0 + 1 & = & 2 > 1 & = & 2 & times & 1 & + & 0 [0.2 cm]
end{array}]
end{tabular}
end{tabularx}
]
end{document}

I propose this variant code, also based on tabularx, but using a matrix
environment and Longstack
for the part under the dashed line:
documentclass{article}
usepackage{geometry}
usepackage{amsmath,bm}
usepackage{tabularx}
usepackage{arydshln, booktabs,}
usepackage[usestackEOL]{stackengine}
geometry{a4paper, total={170 mm,257 mm}, left=20 mm, top=20 mm}
begin{document}
noindenttextbf{Solution:}
[
begin{tabularx}{textwidth}{@{} c | X @{}}
$begin{matrix}
& & 1 & 0 & 1 & 0
times & & & 1 & 0 & 1
midrule
& ^{underline{1}} & 1 & 0 & 1 & 0
& 0 & 0 & 0 & 0 &
1 & 0 & 1 & 0 & &
midrule
1 & 1 & 0 & 0 & 1 & 0
end{matrix}$enspace &
begin{tabular}{@{}p{linewidth}@{}}
As the product of binary multiplication would always be less than~$2$,
it won't generate any carry.

stackMath
[ 1 + 0 + 1 = Longstack{textbf{Product/Sum} 2 > 1} = Longstack{ textbf{Base} 2} times Longstack{textbf{Carry} 1}
+ Longstack{textbf{Result} } ]
end{tabular}
end{tabularx}
]
end{document}
