Why are you using dynamic arrays for vectors/matricies? If what you have is an actual array you wish to grow then + would likely be an append operation.

var
  v: TVec2;
begn
  v := V2(1,1);
  v += 10; // add 10 to x/y  and get: v = 11,11

var
  v: array of float;
begn
  SetLength(v, 1);
  v[0] := 1;
  v += 10; // append 10 and get : v = 1,10
