I'm afraid noone understands what it is you want help with yet. Is it the binary number system?
In that case, it's very much like the decimal system, except each additional digit is worth 2 times as much as the last one as you move to the left, instead of 10 times as much. So in binary, the first digit to the right is worth 1, the second is worth 2, then 4, 8, 16, 32, 64 and so on, instead of 1, 10, 100, 1 000, 10 000, 100 000, 1 000 000, 10 000 000 in decimal.
If you use binary numbers for counting on your fingers, you can actually count from 0 to 1023!
