Vectors can be defined as

Assertion: The difference of two vectors A and B can be treated as the sum of two vectors. Subtraction of vectors can be defined in terms of addition of vectors.

Assertion: The difference of two vectors A and B can be treated as the sum of two vectors. Subtraction of vectors can be defined in terms of addition of vectors.

(A): The division of a vector by another vector is not defined. (R) : The division of a vector by a direction is not possible.
