Oh, ok i see what you have done. Know it should easy for me 2 prove this. Thanks for the help

For all u, v,w, we have v × u = −(u × v) and (u + v) × w = (u × w) + (v × w). Apply these facts to prove, without using co-ordinates, that for all vectors u, v,w, we have u × (v + w) = (u × v) + (u × w). I need help, do not know were to start. Thaks
