A=10, right? A decimal 10 = 1010 in binary. Look below to see how that works out.

nor do I have any idea how MerF got from 010010100111 to 1+2+4+32+128+1024...

To convert from binary to decimal, you add together all the values where the digit is "set" (a "1").
10111001
When the values of the digits are:
128 64 32 16 8 4 2 1
Then we add up all the values where I have a "1". SO, 128+32+16+8+1 = ???
That will be what 10111001 is worth.
