Answer:
What is it that after you take away the whole some still remains?
I stare at you, you stare at me.I have three eyes, yet can't see.Every time I blink, I give you commands.You do as you are told, with your feet and hands.What am I?
You can read me both ways I wear; One way it's a number reversed a snare.
Without me everyone would lose their head.
The more you take away from me the bigger I shall get.
