    Please copy and paste the problem from the given site - along with your thoughts/work.

    Most of us are not willing to go into another site in search of a "problem"!!

    As a (not very active) cacher, I can see the post. Here is the puzzle:

    Mr Boole invented this stuff, and it is an essential part of computing. Translate the info below to get the coordinates. Please note that there are no fractions. Each piece of the puzzle translates to a portion of the coordinates in standard dd mm mmm format, and for this puzzle all 3 pieces are whole numbers. There are two steps for each column to get you to the coordinates. Here is the North.


    110101 10100 1001101100
    AND OR XOR
    111000 01100 0100000101
    ? ? ?


    And here is the West

    0111000 10001 1111000111
    XOR OR AND
    1000011 01011 1001101010
    ? ? ?


    In order to solve this, you can search for "and or xor", to see what those terms mean. The context is "bitwise operations". If you have Windows, the calculator has a programmer mode that can do these operations. It looks like what you have to do next is pretty straightforward.
