Kazza the Blank One

In about year eight (give or take a year) we were learning to solve mathemetical formula such as this one:

Yes really :)

ok so were just learning this stuff in general when a magazine advert came out with the above formula.  Well not quite.  It actually had a mistake in it and didn't work.  So we figured out what was wrong with it and fixed it, and that's what's above.

I can't imagine for a second that anyone will bother to try and solve it, but just in case anyone does, I'll hold off posting the photo from the magazine.
