It tells you that amateur radio uses mostly simple maths until you get to the highest levels - it is all add, subtract, multiply and divide. You plug a couple of numbers into a simple formula, press the right keys on your calculator, and the answer falls out like magic.

Even at the highest levels of the calculations covered barely touch the simplest parts of trigonometry and no algebra, no quadratic equations, no calculus, no statistics are required. The trick is in remembering what formula to use.

Don't forget there are very practical reasons for familiarising yourself with amateur radio mathematics. In electronics, 'plug it in and see if any smoke comes out' is a perfectly valid test method, but one that can get expensive and dangerous.

Doing a little calculation can save a lot of money and heartache. Divided into 24 sections Understanding Amateur Radio Mathematics covers subjects from the fundamentals of amateur radio maths including a chapter called 'the smallest possible amount of Algebra' which explains what algebra is and what it means to you, though the simpler laws to calculating bandwidths, ERP, EIRP, Transmissions lines, even how to make best use of a Smith chart and much more.
