Log Table

Logarithms were introduced by John Napier in 17th century. Initially, it was introduced to simplify calculations of large number multiplication, division etc., Now it is widely used for simplification of exponential functions. Exponential functions are used in radioactivity, population growth etc., Here is a chart of the base 10 logarithmic tables from 1.000 to 9.99.
