"The ABC Song" was first copyrighted in 1835 by Boston music publisher Charles Bradlee. The melody is from a 1761 French music book and is also used in other nursery rhymes like "Twinkle, Twinkle, Little Star", while the author of the lyrics is unknown. Songs set to the same melody are also used to teach the alphabets of other languages.

Logarithms can be used to make calculations easier. For example, two numbers can be multiplied just by using a logarithm table and adding. These are often known as logarithmic properties, which are documented in the table below. [2] The first three operations below assume that x = b c and/or y = b d, so that log b (x) = c and log b (y) = d.
In algebraic geometry and the theory of complex manifolds, a logarithmic differential form is a differential form with poles of a certain kind. The concept was introduced by Pierre Deligne . [ 1 ] In short, logarithmic differentials have the mildest possible singularities needed in order to give information about an open submanifold (the ...
The lyrics and title of the song are a tribute to R&B and soul singer Smokey Robinson. In the United States, Robinson's single " One Heartbeat " and ABC's "When Smokey Sings" were ranked in the Billboard 100 pop chart simultaneously for several weeks, including the week ending 3 October 1987, in which both songs ranked in the top 10.
The graph of the logarithm base 2 crosses the x-axis at x = 1 and passes through the points (2, 1), (4, 2), and (8, 3), depicting, e.g., log 2 (8) = 3 and 2 3 = 8. The graph gets arbitrarily close to the y-axis, but does not meet it. Addition, multiplication, and exponentiation are three of the most fundamental arithmetic operations.
A boundary Q-divisor on a variety is a Q-divisor D of the form Σd i D i where the D i are the distinct irreducible components of D and all coefficients are rational numbers with 0≤d i ≤1. A logarithmic pair, or log pair for short, is a pair (X,D) consisting of a normal variety X and a boundary Q-divisor D.
Historically', the "common logarithm" was known by its Latin name logarithmus decimalis [2] or logarithmus decadis. [ 3 ] The mathematical notation for using the common logarithm is log( x ) , [ 4 ] log 10 ( x ) , [ 5 ] or sometimes Log( x ) with a capital L ; [ a ] on calculators , it is printed as "log", but mathematicians usually mean ...
