... 1~u = ~u. Hence [M4 ] is not a consequence of the other axioms. Solution The proofs of [A1 ], [A2 ], [A3 ], and [A4 ] are straightforward. Note that ~0 = (0, 0) and −(a, b) = (−a, −b). We have k((a1 , b1 ) + (a2 , b2 )) = k(a1 + a2 , b1 + b2 ) = (k(a1 + a2 ), 0) = (ka1 + ka2 , 0) = (ka1 , 0) + (ka2 ...
