so what is this number ?

lets look at it once more. In easier language for you .

There is a ( 1 ) under the binary items. Some have a zero.

There is 1 under the 128 = 128
there is 0 under the 64 = 0
there is 1 under the 32 = 32
there is 0 under the 16 = 16
there is 0 under the 8 = 0
there is 1 under the 4 = 4
there is 1 under the 2 = 2
there is 1 under the 1 = 1
------------

so, add the right hand column together and what do you get ?

I can tell you its 183.

in binary , it would be written as 10100111

------------------------------------------------

a very easy way of doing binary is as follows.

001 = 1
010 = 2
011 = 3
100 = 4
101 = 5
110 = 6
111 = 7
1000 = 8
1001 = 9
1010 = 10

remember the intitial numbers in binary 128 64 32 16 8 4 2 1

I hope this helps some. Its really easy if you remember to double the columns with the lowest number on the right..
