Element by element. That is: Sum all the first elements to get the first element of the result; Sum all the second elements to get the second element of the result...

The vector sum is obtained by adding the two quantities. The vector difference is obtained by subtracting one from the other. Hint: 'sum' always means addition is involved, 'difference' always means subtraction is involved.

That is the algebraic answer. There is also a geometric answer.

To sum vectors a and b, draw vector a. From the tip of vector a, draw vector b. Then a + b is the vector from the base of a to the tip of b. To calculate a - b, instead of drawing b,draw the vector -b, which is a vector of the same magnitude as b but going in the opposite direction.

How do you find the vector sum and vector diffirences of two vector quantities?
