The following proof is solely based on vector space related axioms.
Axiom names are italicised.
They are defined in Wikipedia (see vector space article).
Vector spaces - Multiplying by zero scalar yields zero vector
Let…be…Fa field.Va vector space over F.0an identity element of addition of F.0an identity element of addition of V.van arbitrary vector in V.
Then, 0v=0.
Proof. We will denote by 1 an identity element of scalar multiplication;
we will denote by (−v) an additive inverse of v.
0v=0v+0by Identity element of vector addition=0v+(v+(−v))by Inverse elements of vector addition=(0v+v)+(−v)by Associativity of vector addition=(0v+1v)+(−v)by Identity element of scalar multiplication=((0+1)v)+(−v)by Distributivity of scalar multiplication (field addition)=((1+0)v)+(−v)by Commutativity of field addition=(1v)+(−v)by Identity element of field addition=v+(−v)by Identity element of scalar multiplication=0by Inverse elements of vector addition
