# MANUAL CALCULATION OF LOGARITHMS

How can we calculate the logarithms by hand without using
Here is how to calculate logarithms by hand using only multiplication and subtraction. And this procedure produces digit by digit, so you can stop whenever you have enough digits. Before we do that, let’s give an example so it will be easier to u..

PDF fileCalculating Logarithms By Hand W. Blaine Dowler June 14, 2010 Abstract This details methods by which we can calculate logarithms by hand. 1 De nition and Basic Properties A logarithm can be de ned as follows: if bx = y, then x = log b y. In other words, the logarithm of y to base b is the exponent we must raise b to in order to get y as the result.
LaMarotte: Calculating the Log of a Number by Hand
Calculating the Log of a Number by Hand. I’ve become interested in logarithms—for a reason. This very much increases the efficiency of manual calculation—which was Napier’s motivation for developing logarithms in a time when mechanical calculators,
Logarithm - Wikipedia
OverviewMotivation and definitionLogarithmic identitiesHistoryLogarithm tables, slide rules, and historical applicationsIn mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x. In the simplest case, the logarithm counts the number of occurrences of the same factor in repeated multiplication; e.g., since 1000 = 10 × 10 × 10 = 103, the "logarithm base 10" of 1000 is 3, or log10 = 3. The logarithm of x to base b is denoted as logb, or without..See more on enpedia · Text under CC-BY-SA license

logarithms - What is the best way to calculate log without
Calculating them to high precision is tedious, which is why the tables were once so important. The tables relied on interpolation formulae and inevitably contained errors, carried from book to book as a result of silent copying, sometimes for 200 years or more; errors in Vlacq and de Decker's table (1627) were still turning up in tables in the 19th century.

Logarithm - Simple English Wikipedia, the free encyclopedia
Logarithms or logs are a part of mathematics are related to exponential functions.A logarithm tells what exponent (or power) is needed to make a certain number, so logarithms are the inverse (opposite) of exponentiationorically, they were useful in multiplying or dividing large numbers.
