You basically place zeroes instead of the actual digit to find the value of each number.
Example:
855
800+50+5

If so, you would divide 13.47 by 3.
This would give you $4.49 per yard.
He fourth one: 4,5,6,7,8...if it has those two bars || it means absolute value which basically means if its negative you just change it to a posotive :)
