Moving left again 8 X 1 = 8
Moving left again 16 X 0 = 0
Moving left again 32 X 0 = 0
Moving left again 64 X 0 = 0
Moving left again 128 X 1 = 128

And 1 + 0 + 0 + 8 + 0 + 0 + 0 + 128 = 137

                     Logical Operators <AND> <OR>

When you AND two numbers the results are in a new third number.
For example:
a = 137
b = 105
c = a AND b

1 0 0 0 1 0 0 1  This represents A <137>
0 1 1 0 1 0 0 1  This represents B <105>

0 0 0 0 1 0 0 1  This represents C <9>

What occurs when you AND two numbers is that the computer compares
the bits within the first number against the bits in the second number.
If the bits are the same then they will remain the same in the third number.
If they are not the same then the equivalent bits will be 0
in the third number.


                               "Logical OR

What occurs when you OR two numbers is that the computer compares
the bits within the first number against the bits in the second number.
If the bits are the same they will remain the same in the third number.
If they are not the same then the bits will be 1 in the third number.

For example:
A=122
B=15
C=A OR B

0 1 1 1 1 0 1 0   This represents A <122>
0 0 0 0 1 1 1 1   This represents B <15>

0 1 1 1 1 1 1 1   This represents C <127>

I hope it proves to be of some use to you.
