<p></p> <p><b>New page</b></p><div>An example displays a problem and a sequence of steps leading up to an answer. If the example is &quot;completely justified,&quot; then each of the steps includes a description of the reasoning that generates it, which is usually the application of one or more knowledge components. For instance, Suppose the problem is &quot;Solve 2x+3=10 for x.&quot; A completely justified example, written in traditional 2-column format, is:<br /> <br /> * 2x+3=10 Given<br /> * 2x=10-3 Subtract-both-sides <br /> * 2x=7 Simplify<br /> * x = 7/2 Divide-both-sides<br /> * x = 3.5 Simplify<br /> <br /> The equations are the steps; the text after each equation is its justification.<br /> <br /> [[Category:Glossary]]<br /> [[Category:Ringenberg Examples-as-help]]</div>
