Addition

For addition you need to first identify the X and Y components of your vectors​, this will be the horizontal distance of the vector (X)​ And the vertical distance of the vector (Y) ​Then you add together both the X’s and both the Y’s.

Subtraction

Subtraction is the same as addition but you need to reverse the second vector in the operation​, So if the question asks for (7,8) – (-9,10) , you need to reverse the second vector and then do addition as normal​. The question then becomes (7,8) + (9,-10)​. Solving that gets you (16, -2).
