Fibonacci Number
... two preceding Fibonacci numbers–is called a recursive rule because it defines a number in the sequence using earlier numbers in the sequence. Using subscript notation, the above recursive rule can be expressed by the simple and concise formula FN = FN – 1 + FN – 2 . Copyright © 2010 Pearson Educatio ...

... These fractions might look a little funny, because the numerator (the “upstairs” number) is bigger than the denominator (the downstairs number). Such fractions are called improper fractions, but there’s really nothing at all wrong with them. These examples show that there are multiple ways to write ...

Arithmetic
Arithmetic or arithmetics (from the Greek ἀριθμός arithmos, ""number"") is the oldest and most elementary branch of mathematics. It consists of the study of numbers, especially the properties of the traditional operations between them—addition, subtraction, multiplication and division. Arithmetic is an elementary part of number theory, and number theory is considered to be one of the top-level divisions of modern mathematics, along with algebra, geometry, and analysis. The terms arithmetic and higher arithmetic were used until the beginning of the 20th century as synonyms for number theory and are sometimes still used to refer to a wider part of number theory.
