Asked: Do psychics actually work?

Has anyone ever been to one? For love or money? Did it work? Were you happy with your results? Would you go back? I really want to try it out.

Asked: What is it mean when you add 2 vectors?

What does it mean when you add 2 vectors? I never taken psychics before; I am very limited in my knowledge. I am barely learning what vectors are and I am not exactly sure what it means when you have Va+Vb

I know that vectors is distance with direction but I am not sure what it means when you add them
This will truly help me with understanding. Only link I accept is youtube videos since I had trouble with previous links sent to me.

I will give 5 points to whoever can answer this in the simplest words. Please do not use random terminology that makes others brain shut down since that does not help anyone.
