Answer 1

Answer 2

if so, the right most column is the ones column
and each column to the left is worth twice as much as the column before it

Answer 3

It's not a simple binary number it's a binary coded decimal http://screencast.com/t/i3DrymURM

Answer 4

oh

Answer 5

I can see the screencast this time. Each four digits functions like its own binary number.

Answer 6

And none of the sets of four digits will ever go above 9, so it is an easier way of presenting binary so it can be read into decimal.

Answer 7

It looks like each of these 4 bit packets is like one digit of a 4-digit decimal number

Answer 8

so just read the 4 bit packets separately

Answer 9

8 3 5 9
