Why?  The precedence rules?  Fair enough - sometimes what's tempting  
is bad for you, but you still want to try it anyway!

Err, that's only true in 3D (vectors of length 3).  There's no such  
thing as a cross product between (say) vectors of length 2,4 or  
indeed anything else.  The cross product is, in effect, a restricted  
version of the exterior (wedge) product which exists for higher  
dimensions.
