Octal and Hexadecimal Representation
... This requires knowing the powers of 16 (the powers of 2 are more easily obtained by doubling) and conversion the hexadecimal digits 0xA thru 0xF to 10 thru 15. Horner’s Method also works (?). ...

... We can reduce a fraction by finding common multipliers or factors in the numerator and denominator of a fraction. A fail safe way to do this is to factor a number into the primes of which it is made. We can factor 12 as 2 × 2 × 3. And 2 and 3 are both prime. Definition 1 (Prime Factorization). The p ...

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.
