Well, isn't that just a happy little binary number we have here! When we look at 00001001, we can see that it represents the decimal number 9. Each place in the binary number represents a power of 2, starting from the right with 2^0, then 2^1, 2^2, and so on. So, 0*2^7 + 0*2^6 + 0*2^5 + 0*2^4 + 1*2^3 + 0*2^2 + 0*2^1 + 1*2^0 equals 9.
