A description of how the answer box behaves in the compiled pdf

Answer behavior in the PDF

In the PDF, the default behavior is showing all answers and solutions.

Using \documentclass[handout]{ximera} suppresses the answers.

In the PDF version, is by default rendered as $\answer {x^2 + 3x + 1}$ , and in handout mode normally as $\answer {x^2 + 3x + 1}$ . With you get by default $\answer [given]{x^2 + 3x + 1}$ , but in handout mode $\answer [given]{x^2 + 3x + 1}$ .

Note: in order to make sense of this, you’ll have to consult the PDF version of this manual!

This behavior can be changed by setting \defaultAnswerFormat, \handoutAnswerFormat and \givenAnswerFormat.

Note: only in the PDF interesting things can be seen. Online these settings should not have any effect.

The format of the output of \answer can be adapted. Following code

\begin{tabular}{ll}
 
  long: & $\answer{1234567890}$, and [given]: $\answer[given]{1234567890}$. \\
 
  short:& $\answer{15}$,         and [given]: $\answer[given]{12}$.
 
\end{tabular}

gives by default :

Handout:

long:	$\answer {1234567890}$ and [given]: $\answer [given]{1234567890}$ .
short:	$\answer {15}$ and [given]: $\answer [given]{12}$ .

Default:

long:	$\answer {1234567890}$ and [given]: $\answer [given]{1234567890}$ .
short:	$\answer {15}$ and [given]: $\answer [given]{12}$ .

But could e.g. be changed to (handout: flexible box, default: boxed, and given: plain) with

\let\handoutAnswerFormat\answerFormatFlexibleBox
 
\let\defaultAnswerFormat\answerFormatBoxed
 
\let\givenAnswerFormat\answerFormatPlain

Handout:

long:	$\answer {1234567890}$ and [given]: $\answer [given]{1234567890}$ .
short:	$\answer {15}$ and [given]: $\answer [given]{12}$ .

Default:

long:	$\answer {1234567890}$ and [given]: $\answer [given]{1234567890}$ .
short:	$\answer {15}$ and [given]: $\answer [given]{12}$ .

or also to (handout: fixed length line, default: blue, and given: blue) with

\renewcommand{\answerFormatLength}{3cm}
 
\let\handoutAnswerFormat\answerFormatLine
 
\let\defaultAnswerFormat\answerFormatBlue
 
\let\givenAnswerFormat\answerFormatBlue

Handout:

long:	$\answer {1234567890}$ and [given]: $\answer [given]{1234567890}$ .
short:	$\answer {15}$ and [given]: $\answer [given]{12}$ .

Default:

long:	$\answer {1234567890}$ and [given]: $\answer [given]{1234567890}$ .
short:	$\answer {15}$ and [given]: $\answer [given]{12}$ .

Further formats can be implemented as follows:

(Auto)Scale Box to (Correct) Answer Size:

The answer box scales with the size of the (correct) answer. To do this, include the command

                                                                  

                                                                  
    \renewcommand{\handoutAnswerFormat}[1]{
      
    \fbox{\scalebox{2}{\phantom{$#1$}}}}

in the preamble.

Now $\answer{x^2 + 3x + 1}$ will display as and $\answer{2x}$ will display as .

(Auto)Scaling Horizontal Line:

A horizontal line that scales with the size of the answer. To do this, include the command

    \renewcommand{\handoutAnswerFormat}[1]{\protect
      
    \rule{\widthof{$#1$}*2}{0.4pt}}

in the preamble. The *2 stretched the length by two to accomodate handwriting.

Now $\answer{x^2 + 3x + 1}$ will display as ______________________________ and $\answer{2x}$ will display as ______.
