## Main Question or Discussion Point

2 questions i have;

1. proove that; p x ( q + r ) = p x q + p x r

2. and p x ( q x r ) = ( p x q ) x r

where;

p = p1i + p2j + p3k

q = q1i + q2j + q3k

r = r1i + r2j + r3k

1. proove that; p x ( q + r ) = p x q + p x r

2. and p x ( q x r ) = ( p x q ) x r

where;

p = p1i + p2j + p3k

q = q1i + q2j + q3k

r = r1i + r2j + r3k
