Sodding Sums - The 10% of maths you actually need - E-book - ePub

Maths is a part of everyday life and there's no denying it. For anyone who has blocked distant memories of complicated algebraic formulae or incomprehensible trigonometry, numbers can strike fear at your very core. It is, however, an unavoidable part of life, so why struggle through without a clue? Hywel Carver is passionate about making maths approachable for everyone. In his go-to guide he introduces handy arithme`tricks' that help solve multiplication and division problems with rounding and approximations; explains fractions, percentages and ratios, how to convert between them and understand increases, decreases and multiplication; delves into all types of conversions - metric versus imperial, Celsius to Fahrenheit, as well as distances and speeds.
These mathematical theories can then be applied to common conundrums, such as how mortgages and loans actually work, grasping an understanding of compound interest, the chances and probability of success in gambling games, and how to analyse statistics and data including causality, coincidence and correlation. Sodding Sums will subtract stress and divide difficulty so you no longer feel clueless when challenged by maths.
