Hey guys, wasnt too sure which section to post this in but since its a simply question, id thought u wouldnt mind if i posted it here.

My question is that if i have point A (3,1,1) and point B (2,-3,5), how do i construct a vector from this points.

So for instance, i need to find

vector AB, would this be = (-3+2,-1-3,-1-5)

vector BA, would this be = (3-2,3+1,1-5)

In my text book this seems to be the methods but no way does it state that if u need vector AB, then u substract vector A from vector B. Is this right?
