Hint: Graphical addition/subtraction of vectors use law of parallelograms.

Thank you for replying! I know that Vector C is equal to -v, since with - vectors, it essentially just goes in the opposite direction. However, I am stuck on the 3 addition and subtraction problems. I do not understand how you get an answer to these without having any numbers.

Unless you post answers (right or wrong) to each of those, here is no way we can(will) help you.
Here is a free one: \(\vec{v}+\vec{w}=\vec{g}\). Can you see why? If so tell us. If not say why!

I'm not sure as to why v + w = g? Could you explain why?

Complete the parallelogram (in the given sketch). You now see:

v + w = g

- because g makes one of the diagonals of the parallelogram.

Using your posted diagram, take the blue vector to the tip end of the green vector.
What is the resulting vector?
