Log tables are used to find log and antilog of given number. Log can be calculated as follows ,
 
Suppose we need to calculate log 200 , the see for the verical column and search for 20 then the value below 0 is to be noted which is 3010 , now since there are three digits in the question so subtract 1 from the number of digits and the value becomes 3-1 = 2 , so we get log200 = 2.3010 .
