Grrrr...Vectors (1 Viewer)

I know this is probably not the right place to put this but we have started physics on vectors and i am having trouble understanding some of the question with things such as the Head to Tail Method etc. Has anyone got any advice on understanding this part of physics?

vectors, geometrically are denoted by an arrow.
mathematically, you can say they are denoted by [x, y] if they are 2 dimensional.

let's say on a straight line two vectors are placed head to head (not touching) at points -5 and 5 on the number line.
that means their resultant is [-5, 0] + [5, 0] = [0, 0] (a number line is 1 dimension, so y = 0)

if you cant see vectors geometrically you can try and analyse them mathematically, using trig as well.
