title: Getting an error, "Operator '-=' is ambiguous on operands of type 'Vector3' and 'Vector2'"
body: <p>Alright so I have this basic line of code,</p>
  <pre><code>transform.position -= new Vector2(-1f, 0f);
  </code></pre>
  <p>and for some reason I'm getting this error,</p>
  <pre><code>Operator '-=' is ambiguous on operands of type 'Vector3' and 'Vector2'
  </code></pre>
  <p>I heard this error is about the compiler <em>not knowing which vector you are specifying</em>, but I'm not sure how I'm supposed to <em>specify</em> what <code>transform.position</code> is.</p>
