    The "standard" way to calculate surds with out a calculator is to use taylor expansions to approximate the actual solution. Calculators do a similar thing, expect they use series that converge quicker.


    As is often the case with technical subjects we are presented with an unfortunate choice: an explanation that is accurate but incomprehensible, or comprehensible but wrong.
