I don’t understand the if statement that says if (Speed > Deceleration Time.deltaTime) , how does this stop the object’s speed to 0?

 if ((Input.GetKey("left")) && (Speed < MaxSpeed)) 
 Speed = Speed - Acceleration * Time.deltaTime;
 else if ((Input.GetKey("right")) && (Speed > -MaxSpeed))
     Speed = Speed + Acceleration * Time.deltaTime;
 else {
     if (Speed > Deceleration Time.deltaTime) 
     Speed = Speed - Deceleration * Time.deltaTime;
     else if (Speed < -Deceleration Time.deltaTime) 
         Speed = Speed + Deceleration * Time.deltaTime;
     else Speed = 0;
 }
 transform.position.x = transform.position.x + Speed * Time.deltaTime;

It’s simply missing a multiplying asterisk
if (Speed > Deceleration * Time.deltaTime)
meaning if your speed is over your stated minimum (which is deceleration), it will decrease.
