A set X of elements called vectors. 3. An operation called vector addition that associates a sum x+y ∈ X with each pair of vectors x,y ∈ X such that • Addition is commutative: x+y = y +x • Addition is associative: x+(y +z) = (x+y)+z • There exists an element 0 ∈ X, called the zero vector, for which x+0 = x, ∀x ∈ X
