Sure, you can define a method in a declaration. It will become a
method of the page implementation class, so you can call it from any
other scripting elements on the page.
For example:
<html>
<body>
Fact(4) = <%= fact(4) %><br>
Fact(5) = <%= fact(5) %><br>
Fact(6) = <%= fact(6) %><br>
<%! public long fact (long x) {
if (x == 0) { return 1; }
else return (x * fact(x-1));
} %>
</body>
</html>
