This package was designed with specifically +mathematics problems in mind, but can be used for other +subjects as well. The idea is to create a file containing a +large number of problems with their solutions which can be +read in by L<SUP><SMALL>A</SMALL></SUP>T<SMALL>E</SMALL>X, and then select a number of problems to +typeset. This means that once the database has been set up, +each year you can easily create a new problem sheet that is +sufficiently different from the previous year, thus +preventing the temptation of current students seeking out +the previous year's students, and checking out their +answers. There is also an option that can be passed to the +package to determine whether or not the solutions should be +printed. In this way, one file can either produce the +student's version or the teacher's version. + +<P> + +<H1><A NAME="SECTION00030000000000000000"> +Package Options</A> +</H1> +The following options may be passed to this package: +<DIV ALIGN="CENTER"> +<TABLE CELLPADDING=3> +<TR><TD ALIGN="LEFT"><TT></TD><TD ALIGN="LEFT">answers </TT></TD> +<TD ALIGN="LEFT">Show the answers</TD> +</TR> +<TR><TD ALIGN="LEFT"><TT></TD><TD ALIGN="LEFT">noanswers </TT></TD> +<TD ALIGN="LEFT">Don't show the answers (default)</TD> +</TR> +</TABLE> +</DIV> + +<P> + +<H1><A NAME="SECTION00040000000000000000"> +Creating a New Problem</A> +</H1> + +<A NAME="newproblem"></A><TT>newproblem</TT><A NAME="386"></A><code>[</code><I>nargs</I><code>]{</code><I>label</I><code>}{</code><I>problem</I><code>}{</code><I>solution</I><code>}</code> +<BR> +<BR> +A new problem is defined using the command +<TT>\newproblem</TT><A NAME="389"></A>.

Three counters can be defined to represent the +three coefficients: +<PRE> +\newcounter{A} +\newcounter{B} +\newcounter{C} +</PRE> +Random values can now be assigned to these counters: +<PRE> +\random{A}{-5}{5} +\random{B}{-5}{5} +\random{C}{-5}{5} +</PRE> +Finally, the problem can be used (note the use of <TT>\arabic</TT><A NAME="486"></A>): +<PRE> +\useproblem{diff:quad}{\arabic{A}}{\arabic{B}}{\arabic{C}} +</PRE> + +<P> +The command +<A NAME="doforrandN"></A><TT>doforrandN</TT><A NAME="490"></A><code>{</code><I>n</I><code>}{</code><I>cmd</I><code>}{</code><I>list</I><code>}{</code><I>text</I><code>}</code> will apply +<I>text</I> for a random selection of <I>n</I> items in the +comma separated <I>list</I>. In each iteration the list +item is denoted by <I>cmd</I>. For example, suppose you +have three files called <TT>file1.tex</TT>, +<TT>file2.tex</TT> and <TT>file3.tex</TT>, and you want to +select 1 problem from two of the three files, then you can +do: +<PRE> +\doforrandN{2}{\file}{file1,file2,file3}{\selectrandomly{\file}{1}} +</PRE> +Note that it is also possible to do +<PRE> +\newcounter{numproblems} +\random{numproblems}{1}{3} +\selectrandomly{file\arabic{numproblems}}{1} +\random{numproblems}{1}{3} +\selectrandomly{file\arabic{numproblems}}{1} +</PRE> +however there is a possibility that the same file may be +selected twice which will cause an error. + +<P> +The command <A NAME="showanswers"></A><TT>showanswers</TT><A NAME="494"></A> will show the solutions from +that point on. May be localised by placing within a group. + +<P> +The command <A NAME="hideanswers"></A><TT>hideanswers</TT><A NAME="498"></A> will hide the solutions from +that point on. May be localised by placing within a group. + +<P> +The solution is placed inside the <TT>solution</TT> +environment. By default this environment simply does +<code>\par\noindent\textbf{\solutionname:} </code> at the start, where +<A NAME="solutionname"></A><TT>solutionname</TT><A NAME="503"></A> +has the value: Solution. See the file <TT>sample3.tex</TT>, which +comes with this package, for an illustration of how to +customise the way in which the randomly selected problems are +displayed. This sample file randomly selects multiple choice +problems stored in the file <TT>tabmchoice.tex</TT>, and displays them +in a longtable <TT>environment</TT>. As from version 2.03, the package +will not define this environment if another package or class file has +already defined it. + +<P> +The boolean variable <TT>showanswers</TT> is defined to be +true if the answers are shown and false otherwise. You can +therefore do something like: +<PRE> +\ifthenelse{\boolean{showanswers}}{\textbf{Solution Sheet}}{} +</PRE> +and <B>Solution Sheet</B> will be printed only if the +answers are displayed.
