I forgot the name of the mathematical function that does it so it's difficult to google it, specially in english !

The idea is to find the object that transforms a number into its negative version : "x" becomes "-x" or "-x" becomes "x".

My mathematical courses are very far away...

0 - x would work, right?

right...

*ouch*

I'm ashamed... I wasn't so bad in math when i was young, that was some times ago. In fact I have some excuses : there is a object making 1/x... So I thought there could be one that does -X...

Don't sweat it. We all have brain farts.

Brain farts... didn't that one ! farts from... fart ? Sorry, I'm french (xcuse my french !). I need to remember that one !

In y case it's not a fart, it's a hurricane...
