Show how the axioms for a vector space V can be used to prove the elementary properties

Question:

Show how the axioms for a vector space V can be used to prove the elementary properties described after the definition of a vector space. Fill in the blanks with the appropriate axiom numbers. Because of Axiom 2, Axioms 4 and 5 imply, respectively, that 0 + u = u and - u + u = 0 for all u.

Fill in the missing axiom numbers in the following proof that 0u = 0 for every u in V .
