expressions in statements must only be executed for their side effects
here is my unfinished race car script
var movespeed = 0;
var turn = 0; // plus for right, minus for left
var maxspeed = 16;
var minspeed = -8;
function Update () {
transform.Translate(Vector3.left * Time.deltaTime * movespeed);
transform.Rotate(Vector3.up * Time.deltaTime * turn);
if (Input.GetKey("a")){
turn - 3;
}
if(Input.GetKey("d")){
turn + 3;
}
if (Input.GetKey("w")){
movespeed + 0.5;
}
if (Input.GetKey("s")){
movespeed - 1;
}
if (movespeed >= maxspeed){
movespeed = maxspeed;
}
if (movespeed <= minspeed){
movespeed = minspeed;
}
}
im getting the error "expressions in statements must only be executed for their side effects" at
turn - 3;
turn + 3;
movespeed + 0.5;
movespeed + 1;
does anyone know what the problem is?

You're doing it wrong - the variable increment must be done this way:
turn -= 3;
turn += 3;
movespeed += 0.5;
movespeed += 1;
