+
+<dl>
+<dt><nobr>(+ <i>expr1</i> ...)</nobr></dt>

+<h2>Description</h2>
+
+<p>The '+' function adds a list of numbers together and returns the
+result.</p>
+
+<h2>Examples</h2>
+
+<pre class="example">
+(+ 1)         =&gt; 1
+(+ 1 2)       =&gt; 3
+(+ 1 2 3)     =&gt; 6
+(+ 1 2 3 4)   =&gt; 10
+</pre>
+
+<pre class="example">
+&gt; (print (+ 1 2 (* 3.5 (/ 3.9 1.45))))
+12.4138  <font color="#008844">; screen output of PRINT</font>
+12.4138  <font color="#008844">; return value</font>
+</pre>
+
+<p>See <a href="multiplication.htm">&nbsp;*&nbsp;</a>,
+<a href="division.htm">&nbsp;/&nbsp;</a>, <a href="print.htm">print</a>.
+XLISP first prints the value on the screen, the second number is the
+return value.</p>
