title: What does vector minus vector actually mean
body: <p>Trying to understand (did not take many math classes, so I apologize I know I should know this) what it means when I have some code that takes 2 vectors and subtracts one from the other to equal a new vector. I kind of get what a vector in unity is, it's like a point with 3 numbers that represent it's position in the world. But what I am confused about is when I have this for instance </p>
  
  <pre><code>Transform target = GameObject.FindWithTag ("Player").transform;
  Vector3 targetDir = target.position - transform.position;
  </code></pre>
  
  <p>So I obviously know what subtraction means, but what I am trying to understand is what the new targetDir is since you're subtracting 2 points, not numbers. Do you simply just minus the equivalent axis (x-x, y-y, z-z) and that gives you the new vector? </p>
