Why were logarithms invented?

Logarithms were invented by John Napier who was a mathematician. He invented other things too, so there was no reason why he couldn't invent the logarithms. Logarithms were invented so people could take short cuts to multiplications! :)


Who was it invented?

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 is the natural logarithms in mathematics?

Natural logarithms are logarithms to base e, where e is the transcendental number which is roughly equal to 2.71828. One of its properties is that the slope (derivative) of the graph of ex at any point is also ex.
