        <questionStem>\subsection*{How do I navigate around the page?}

{\em Do not use your browser&apos;s &quot;Back&quot; or &quot;Reload&quot; buttons during the test.}

\par You may choose to view a test either in focused mode, or in unfocused mode.  Focued mode gives you one question at a time, and unfocused mode shows the whole test on one long scrolling screen.  It is possible to switch between the two modes during a test. 

\par Once you&apos;ve given your answers, you can check there are no syntax errors by pressing the {\bf Validate} link.  
This is at the top and the bottom of each page.  You can change your answer and press validate as often as you need to. When you are happy with your answer click the {\bf Mark} link to mark your work. Again, you will usually be able to change an answer and either validate or mark again.

{\em After you have requested the solutions you will not be able to change your response.} 

\par Some questions are randomly generated, so different students will get different questions.  This is to discourage cheating by copying the work of others! 

\subsection*{How do I enter my answers?} 

You should type in your answers using the same syntax used by the symbolic mathematics package {\em Maxima}.  If you are not sure how to do this you can always press the help link on this page.  This will not alter your current test.

\par Try the following questions to familiarize yourself with the question types before using the system for real.  {\bf This is not a test that &quot;counts&quot;}.

\subsection*{Entering basic formulae}
Entering numbers is simple: just type the value.

Enter the number answer to the sum $2+2$.

\begin{itemize}
\item Use a star for multiplication: for example, 3x should be entered as {\tt 3*x}. 
\item Use a `caret&apos; for raising something to a power. You can get a caret by holding down the SHIFT key and pressing the 6 key on most keyboards. \end{itemize}
\par You will often have to enter algebraic answers such as

        <questionStem>\subsection*{Brackets}
Brackets are important to group terms in an expression.  This is particularly the case in STACK since we use a {\em one dimensional input} rather than traditional written mathematics.   When in doubt, use brackets, and also the validate button to display your input in two dimensional form. 

For example to enter powers such as \[2^{x+1}\]
&lt;html&gt;you need to type &lt;tt&gt;&lt;font color=&quot;ORANGE&quot;&gt;2^(x+1)&lt;/font&gt;&lt;/tt&gt;&lt;p&gt;&lt;font color=&quot;red&quot;&gt; The next most common source of errors is missing brackets.&lt;/font&gt;&lt;/p&gt;&lt;/html&gt;
