Scientific Notation – Tutorial
... Science deals with both very large and very small numbers. For example, the diameter of the Earth is about 13,000,000 meters. The radius of a hydrogen atom is 0.00000000012 meters. Consequently,scientists use a "shorthand" way (scientific or exponential notation) to write very large or very small nu ...

Every Fraction Can Be Written As a Decimal
... 1.Always use “and” between the whole number and the decimal to show where the decimal point is. (Never say “and” when you are reading a number without a decimal.) 2.The decimal always has the name of the last digit’s place value even if there are nonzero digits in the other places. For example, if t ...

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.
