Here's an example of how to read the logarithm tables.  Let's assume that I want to find the logarithm of 1.013.  On the table below, I'll look for the number 1.010 in the column on the left, and for 0.003 on top, because the sum of these numbers is 1.013.  Where those numbers intersect (like on a multiplication table) is where the logarithm is - in this case, 0.00560945.
