Question 1171707

<pre>
If you look at the first two rows of the table, and replace each entry with its current value mod 12 (the remainder when divided by 12) you will get:

        1    2    3    4    5     6    7
        ---------------------------------
        4    5    6    7    8     9
             3    2    1    0     11   10


Now 5018 mod 12 = 2  so  5018 lands under column 3.    

To compute modulo 12 on a calculator (assuming it does not have a 'mod' button), divide 5018 by 12 as normal, then subtract the whole number portion from the result.  Multiply the decimal portion (which is the remainder) by 12 to get an integer.
