Two methods can be used for vector addition. (1) Graphically. Place the vectors head-to-tail, without changing their direction or size. (2) Analytically, that is, mathematically. Add the x-component and the y-component separately. The z-component too, if the vectors are in three dimensions.

What is the vector sum of 7 and 5 and 13 and -5?
The whole point of a vector is that it has a magnitude and a direction. There are no directions given in the above string of numbers.
