## Subtopics

- Elementary function [r]: Mathematical functions built from a finite number of exponentials, logarithms, constants, one variable, and roots of equations through composition and combinations using the four elementary arithmetic operations (+ – × ÷).
^{[e]}

- Discrete logarithm [r]: The problem of finding logarithms in a finite field.
^{[e]} - Elementary algebra [r]: A fundamental and relatively basic form of algebra taught to students who are presumed to have little or no formal knowledge of mathematics beyond arithmetic.
^{[e]} - Exponent [r]: A mathematical notation used to represent the operation of exponentiation. It is usually written as a superscript on a number or variable, called the base. For example, in the expression, the base is 5 and the exponent is 4.
^{[e]} - Power law [r]: A mathematical relationship between two quantities where one is proportional to a power of the other: that is, of the form where and are constants, with being referred to as the exponent.
