   Its online program, Zearn Math, was founded in 2012 [1] and helps elementary school students [2] explore and make sense of mathematical concepts. [1] The organization develops digital lessons and curriculum for teachers, school districts and state education agencies and provides data on math learning. [3] Zearn’s curriculum is used in both ...

3. Logarithm - Wikipedia

   en.wikipedia.org/wiki/Logarithm

   e. In mathematics, the logarithm is the inverse function to exponentiation. That means that the logarithm of a number x to the base b is the exponent to which b must be raised to produce x. For example, since 1000 = 103, the logarithm base of 1000 is 3, or log10 (1000) = 3.

4. Natural logarithm - Wikipedia

   en.wikipedia.org/wiki/Natural_logarithm

   The natural logarithm of a number is its logarithm to the base of the mathematical constant e, which is an irrational and transcendental number approximately equal to 2.718 281 828 459. [1] The natural logarithm of x is generally written as ln x, loge x, or sometimes, if the base e is implicit, simply log x.

   Logarithmic scale. of the Internet host count over time shown on a logarithmic scale. A logarithmic scale (or log scale) is a method used to display numerical data that spans a broad range of values, especially when there are significant differences between the magnitudes of the numbers involved. Unlike a linear scale where each unit of ...

8. Discrete logarithm - Wikipedia

   en.wikipedia.org/wiki/Discrete_logarithm

   Discrete logarithm. In mathematics, for given real numbers a and b, the logarithm log b a is a number x such that bx = a. Analogously, in any group G, powers bk can be defined for all integers k, and the discrete logarithm log b a is an integer k such that bk = a. In number theory, the more commonly used term is index: we can write x = ind r a ...

9. Log-normal distribution - Wikipedia

   en.wikipedia.org/wiki/Log-normal_distribution

   Log-normal distribution. In probability theory, a log-normal (or lognormal) distribution is a continuous probability distribution of a random variable whose logarithm is normally distributed. Thus, if the random variable X is log-normally distributed, then Y = ln (X) has a normal distribution.
