Trying to understand this line of code

Hi gurus,

This might be a very simple question to you guys, but I can't find any example demostrating the following "-" operator infront of an variable from the internet. So I am assuming ResultNumber = 9 which the - operator subtract 1? Please correct my understanding. Thanks

ResNumber = 10.

<ResultNumber><xsl:value-of select="-$ResNumber"/></ResultNumber>

"-" here is a unary minus operator. If $x is 10, then -$x is -10.

Thanks again michael! I gotta buy your book to learn more of XSLT, currently I am working on an integration project which I need to understand what the xslt code do. I don't have any xslt knowledge before this and I only started learning 3 weeks ago.
