Example of a Single Algebraic Answer

To see the following question as it would be presented by the gateway, select here. You need a browser with forms capability for this to work.

In the following example, we have omitted some beginning and ending material that is standard HTML. See the section showing the complete source file template for more information. We do show all the material between the <QUESTION...> and </QUESTION> tags.

The Question

First, we indicate the type of question and give the text of the question itself.

	<QUESTION TYPE=Single-Expression>
	
	Using vector notation, vector <B>A</B>=<VAR>3i+4j</VAR>. 
	Vector <B>B</B>=<VAR>-i+2j</VAR>.  What is the sum of
	these two vectors, <B>A</B>+<B>B</B>?

The Answer

Then we give the correct answer (remember that the <ANSWER...> causes a form to be automatically included in the text; this will allow the reader to submit her answer). Also note that it is safer to wrap the expression of the answer in double quotes.
	<ANSWER ans="2i+6j">

The Responses

No <RESPONSES>. . .</RESPONSES> section is given, therefore the tutorial gateway will automatically generate default responses for all submitted answers. See multiple-choice example 1 for examples of explicitly provided responses.

The Hints

Hints are quite appropriate for this question. Here are the two supplied:
	<HINTS>
	<HINT> Add the numeric values of the components.
	<HINT> The answer is <VAR>2i+6j</VAR>.
	</HINTS>

The End

All questions end with this:
	</QUESTION>
