Here is one, by GingerAle and Hectictar, that Hectictar just asked me to include.  Thanks Girls :)

This is the original thread but I will includ most of the salient coding underneath.

$$\boxed{3x\stackrel{?}{=}7}$$

\boxed{3x\stackrel{?}{=}7}

---------------------------------

$$\begin{array}{|rcll|} \hline \angle {ABC} &=& 27° \\ \measuredangle{ABC} &=& 27° \\ \stackrel {\; \frown} {ABC} &=& 27° \\ \stackrel { \hspace{.1em} \wedge} {AC} &=& 27° \\ \stackrel {\, \hspace{.1em} \frown} {AC} &=& 27° \\ \hline \end{array}\\\ \overset{\; \frown}{AC} = 27° \\$$

Coding

\begin{array}{|rcll|}

\hline

\angle {ABC} &=& 27° \\

\measuredangle{ABC} &=& 27° \\

\stackrel {\; \frown} {ABC} &=& 27° \\

\stackrel { \hspace{.1em} \wedge} {AC} &=& 27° \\

\stackrel {\, \hspace{.1em}  \frown} {AC} &=& 27° \\

\hline \end{array}\\\

\overset{\; \frown}{AC} = 27° \\

I only just realised that Ginger has not used the \boxed command.

I wonder how she got the vertical side lines on her box??   I'll have to work it out ://

Arr got it, it is a part of the array command.

Thanks Ginger :)

Oh Hectictar also mentioned that there is a number of ways to get the degree sign.

These are Hectictars words:

"I have noticed that there are actually two signs that look like degree signs in the "special character" selection. One of them is a masculine ordinal indicator: º  and the other is the degree sign: °  . (If you hover over the symbol it tells the name of it.)

I just use the command   ^\circ     Like this     5^\circ  displays as  $$5^\circ$$
