    A vector space is a set that is closed under finite vector addition and scalar multiplication. The basic example is -dimensional Euclidean space , where every element is represented by a list of real numbers, scalars are real numbers, addition is componentwise, and scalar multiplication is multiplication on each term separately.

    For a general vector space, the scalars are members of a field , in which case is called a vector space over .
    Euclidean -space is called a real vector space, and is called a complex vector space.
    In order for to be a vector space, the following conditions must hold for all elements and any scalars :
    1. Commutativity:











    (1)



    2. Associativity of vector addition:











    (2)



    3. Additive identity: For all ,











    (3)



    4. Existence of additive inverse: For any , there exists a such that











    (4)



    5. Associativity of scalar multiplication:











    (5)



    6. Distributivity of scalar sums:











    (6)



    7. Distributivity of vector sums:











    (7)



    8. Scalar multiplication identity:

    Let be a vector space of dimension over the field of elements (where is necessarily a power of a prime number). Then the number of distinct nonsingular linear operators on is

    and the number of distinct -dimensional subspaces of is

    thank's alot shady
    sorry but i have one qut.
    this topic in geometry or topology
    i think in top
    then vector space the same of the meaning of top. space?????????
    shady this properties remember me by function analysis right
