Arithmetic


Arithmetic or arithmetics (from the Greek word ????µ?? = number) is the oldest and most elementary branch of mathematics, used by almost everyone, for tasks ranging from simple day-to-day counting to advanced science and business calculations. It involves the study of quantity, especially as the result of combining numbers. In common usage, it refers to the simpler properties when using the traditional operations of addition, subtraction, multiplication and division with smaller values of numbers. Professional mathematicians sometimes use the term (higher) arithmetic when referring to more advanced results related to number theory, but this should not be confused with elementary arithmetic.

Maximus in Minimis : Aphlorisms in Unistiches

By: Florentin Smarandache

Etymologically, aphorism + floral = aph(L)orism, which is a short reflection written on a floral design, or a short poetry accompanied by an artistic background. They are colorful contemplations.

FOREWORD If properly designed, any basic air monitoring programme can provide the data required to develop an air pollution control programme. Analyses of the data collected should relate directly to the purpose, or purposes, of the monitoring programme, the three most common being: (1) to observe trends; (2) to judge compliance with air quality standards and to evaluate control strategies; and (3) to evaluate risk to human health. Other analyses may also be important fo...

Language, Proof and Logic

By: John G. Kemeny

Mathematics document containing theorems and formulas.

Excerpt: The special role of logic in rational inquiry. What do the fields of astronomy, economics, finance, law, mathematics, medicine, physics, and sociology have in common? Not much in the way of subject matter, that's for sure. And not all that much in the way of methodology. What they do have in common, with each other and with many other fields, is their dependence on a certain standard of rationality. In each of these fields, it is assumed that the participants ca...
