+148 Arithmetic or arithmetics (from the Greek word ἀριθμός, arithmos "number") is the oldest[1] and most elementary branch ofmathematics. It consists in 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 termsarithmetic and higher arithmetic were used until the beginning of 20th century as synonyms for number theory, and are, sometimes, still used to refer to a wider part of number theory.[2]
