How was logarithm table made?

Logarithm tables were created by calculating the logarithms of numbers using mathematical techniques, primarily the properties of exponents and logarithms. Early mathematicians, like John Napier in the 17th century, developed these tables to simplify complex calculations, particularly in fields like astronomy and navigation. The tables were generated using a base (commonly base 10 or base e) and included a range of numbers, with logarithmic values computed through systematic arithmetic methods. Once established, the tables allowed users to quickly find logarithmic values for multiplication and division, making calculations much faster.
