I can't move my box I made

Question

Here is the problem, I made a box using

\begin{tabular}[b]{|l|}
\hline
example \\
\hline
\end{tabular}

I have the [b] meaning bottom, but the position never changes ... In general how do I manipulate the box to where I want it to be?

Please no fancy packages to install, I am new to this stuff

EDIT: Does anyone know how to add the boxes within \begin{align*} ... \end{align*}?

Answer 1

tabular is non - floating body. Hence you need not use [b] for it. Remove the option and put the code where you want the box to appear. It does the job.

The following example shows various possibilities of placing the box (Still I am afraid that it is not clear to me where to place the box according to the question)

\documentclass{article}    
\usepackage{lipsum}
% ----------------------------------------------------------------
\begin{document}
% ----------------------------------------------------------------
\lipsum[1]
\hspace*{\fill}
\begin{tabular}{|l|}
    \hline
     example \\
     \hline
     \end{tabular}

\begin{parbox}[t]{0.818\textwidth}%
\hfill
\begin{tabular}{|l|}
    \hline
     example \\
     \hline
     \end{tabular}
\end{parbox}
%
\begin{minipage}[c]{\textwidth}
\hfill
\begin{tabular}{|l|}
    \hline
     example \\
     \hline
     \end{tabular}
\end{minipage}

\begin{minipage}[c]{\textwidth}
\centering
\begin{tabular}{|l|}
    \hline
     example \\
     \hline
     \end{tabular}
\end{minipage}
\begin{minipage}[l]{\textwidth}
\begin{tabular}{|l|}

     \hline
     \end{tabular}
\end{minipage}
\lipsum[2]
