Logarithms were introduced by John Napier in the early 17th century as a means to simplify calculations .the present-day notion of logarithms comes from Leonhard Euler, who connected them to the exponential function in the 18th century.
John Napier of Merchiston. A Scotsman developed logarithms. He published his work in 1614. NB Modern calculators have logarithmic tables integrated into them. However, to multiply say . 45 X 2.67. It can be done by Long Multiplication. However, using 'log tables', it becomes an addition. Hence log 123.45 = 2.09149 log 2.67 = 0.42651 Add the logs. 2.09149 + 0.42651 = 2.518 Anti log ( 2.518) = 329.60971 This compares favourably with direct multiplication at 329.6115 You can use logs for division too!!! Except that you subtract the log values. NB The is a book of Log. Tables. ; 'Castle's Four Figure Tables'. You can also change the log. bases using the formula log(a) b = log(c)b / log(c)a. , where the base is changed from 'a' to 'c' ; '10' to 'e' on a calculator.
what if I give you the wrong answer
The Law of the Twelve Tables was Rome' first written and published code of law.
Serial number tables, if published
You look them up in log tables, or use a scientific calculator. The calculators use a method based on the Taylor series.
You calculate the z-scores and then use published tables.

The Beaver Log
No published sn tables in the public domain.
They were inscribed on bronze tablets and displayed at the Roman forum
Without antilog tables or a scientific calculator you cannot. Antilog(x) is usually 10x or ex and that is not simple to calculate.
the worst conductors of heat are wood, plastic, rubber, and cloth.
