lol, you people make bin sound hard Its really simple....
there is 8 collums, 128, 64, 32, 16, 8, 4, 2, and 1
128.....64.....32.....16.....8.....4.....2.....1
now you simply fill everything with zeros to start with
128.....64.....32.....16.....8.....4.....2.....1
--------------------------------------------------
..0........0.......0.......0......0.....0.....0.....0
Now choose a number, lets say 84, you start from the left hand of the chart, and see if the number fits in the number that is there, if it does, replace the 0 under it with a 1, if it doesnt, leave it as a 0 and move on to the next number. Then take your number and minus the number that was there (if you just started, it would be 128) and you got your new # to work with in the 2nd collum. Now lets work with 84 as our #.
84 is not larger than 128, so you leave the first collum as a 0
Our # = 0
84 is larger than 64, so you do 84-64=20, and put a 1 under it
Our # = 01
20 is not larger than 32, so put a 0 there
Our # = 010
20 is larger than 16, so 20-16=4, and put a 1 under it.
Our # = 0101
4 is not larger than 8, so put a 0 there.
our # = 01010
4 is = 4 so you put a 1 and the rest of the collums are 0's
Our # = 01010100
Simple isnt it? BTW for the clock you dont need to know binary, all you need to know is how to add
