what is the use of vector space

To represent the quantity wich have both magnitude and direction.

that i know. i need the use of it

 

By understanding laws of vectors we can represent a physical quantity wich has both magnitude and direction in mathematical form ,also with selecting a reference point . By understanding laws of vector we can predict the resultant vector of two or more vecor’s magnitude and direction by triangle law of vector , parallogram law of vector & polygon law of vector. But in case of scalar we can’t predict the direction .
