To look up a logarithm of say, 15.27, you would First work out the characteristic, in this case it is 1 Run your index finger down the left-hand column until it reaches 15 Now move it right until it is on column 2 (it should be over 1818) Using another finger, find the difference on column 7 of the differences (20) Add the difference.

So the logarithm of 15.27 is 1.1818 + 0.0020 = 1.1838
