... Students should mentally calculate 5%, 10%, 20%, 30%, etc. of a number by first determining 10% of the number. EX: If 10% of 120 is 12, then 5% of 120 is 6 and 20% of 120 is 24. 16. Develop and apply divisibility rules for 2,3,4,5,6,8,9, and 10. See pg. 12 17. Addition, Subtraction and Multiplicatio ...

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.
