10 Axioms
1. the set V is closed under vector addition, that is , x +y € V
2. The set V is closed under scalar multiplication, That is c1 · x E V
3. Vector addition is commutative, that is x + y = y +x
4. vector addition is associative, that is (x + y)+z = x+ (y + z)
5. There is a zero vector 0 E V such that x + 0
= x for all x € V
6. For each x there is a unique vetro
-x such that x+ (-x) = 0
7. (С1 + c2) : х — Сіх + с2х
8. c1 · (x+ y) = c1 · x + c1•y
9. (c1c2) · x = cı•)c2 · x)
10. 1: х —Х
