classifying polygons
... A triangle is a polygon having exactly three sides and three angles inside. The angle sum of a triangle is 180°. • A triangle having all the sides length equal is called an equilateral triangle. • A triangle having two sides of equal length is called an isosceles triangle. • A triangle having no sid ...

... Theorem 1: Let b be a positive integer greater than 1. Then if n is a positive integer, it can be expressed uniquely in the form: n = akbk + ak-1bk-1 + …. + a1b + a0 where k is a nonnegative integer, a0,a1,…. ak are nonnegative integers less than b, and ak≠ 0. The aj, j = 0,…,k are called the base-b ...

Scientific Notation
... Chemists use scientific notation to write very small and very large -numbers. Scientific notation allows a very large or very small number to be written as a number between 1 and 10 multiplied by a power of 10. By expressing numbers in this way, scientific notation makes calculating easier. The most ...

Approximations of π
Approximations for the mathematical constant pi (π) in the history of mathematics reached an accuracy within 0.04% of the true value before the beginning of the Common Era (Archimedes). In Chinese mathematics, this was improved to approximations correct to what corresponds to about seven decimal digits by the 5th century.Further progress was made only from the 15th century (Jamshīd al-Kāshī), and early modern mathematicians reached an accuracy of 35 digits by the 18th century (Ludolph van Ceulen), and 126 digits by the 19th century (Jurij Vega), surpassing the accuracy required for any conceivable application outside of pure mathematics.The record of manual approximation of π is held by William Shanks, who calculated 527 digits correctly in the years preceding 1873. Since the mid 20th century, approximation of π has been the task of electronic digital computers; the current record (as of May 2015) is at 13.3 trillion digits, calculated in October 2014.
