... A number that divides exactly into another number (no remainder), e.g. 1 x 6 = 6, 2 x 3 = 6 so 1,2,3,6, are factors of 6, also x and y are factors of xy A multiple is in the times table of that number e.g. 3,6,9,12,15 are multiples of 3 x, 2x, 3x, 4x are multiples of x ...

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.
