Logarithm tables help you work with logarithms without using a calculator. Calculating a logarithm can be a long process. A table eliminates the need to perform extra math. If you need a specific logarithm, you simply look it up. The calculator was invented in the 1970's. Before that, people used slide rules or tables of logarithms. Using the tables of logarithms, you could perform multiplication, division, find roots or powers - and do all of that fairly easily.
The actual calculations to get a logarithm are quite complicated; in most cases you are better off if you look the logarithm up in tables, or use a scientific calculator.
The logarithm of 22.15 can be calculated using a scientific calculator or logarithm tables. For base 10 (common logarithm), the value is approximately 1.345. If you need the natural logarithm (base e), it is about 3.086. The specific value depends on the base you are using for the logarithm.
To find a logarithm, you need to determine the power to which a given base must be raised to produce a specific number. The logarithm can be expressed as ( \log_b(a) = c ), meaning ( b^c = a ), where ( b ) is the base, ( a ) is the number, and ( c ) is the logarithm. You can use logarithm tables, calculators, or software tools to compute logarithms for various bases, such as base 10 (common logarithm) or base ( e ) (natural logarithm).

Pythagora discovered time tables
Besides using a calculator, there are tables of logarithms. You can find the antilog that way. See the related link.

Charles Babbage. His computer was intended to produce logarithm talbes used in navigation.
The simplest way to do it is to use Logarithms, from a book of Logarithmic Tables and Anti-logarithms. You simply look up the Logarithm of your quantity, then divide that quantity by 2 , and then look up its Anti-logarithm. that will give you the answer.
The natural logarithm is the logarithm having base e, whereThe common logarithm is the logarithm to base 10.You can probably find both definitions in wikipedia.
