... The division axiom is an axiom of equality. If equal quantities are divided by the same or equal values, the quotients are equal. E.g., If a = b then a / 4 = b / 4. The axiom therefore can be expressed as: If a = b and c = d then a / c = b / d. Note: No number can be divided by zero; it is an undefi ...

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.
