RELATIVISTIC ADDITION AND GROUP THEORY 1. Introduction
... (We write the identity for ∗ as u rather than, say, e, since we’re working with real numbers and don’t want any confusion with the real number 2.71828...) It will be useful to write the operation x ∗ y in the notation of a function of two variables: F (x, y) = x ∗ y. For example, the classical and r ...

Operations with Integers and Rational Numbers Note
... - add or subtract numerators, denominator stays the same - then reduce to lowest terms - if you have a mixed fraction, you need to first change it to an improper fraction and then find a common denominator, add or subtract, and reduce to lowest terms ...

Mathematics of radio engineering
The mathematics of radio engineering is the mathematical description by complex analysis of the electromagnetic theory applied to radio. Waves have been studied since ancient times and many different techniques have developed of which the most useful idea is the superposition principle which apply to radio waves. The Huygen's principle, which says that each wavefront creates an infinite number of new wavefronts that can be added, is the base for this analysis.
