From basic multiplication and division to fractions, decimals, and algebra, to Euclidean geometry, this is the all-in-one place to refresh math skills! The quick-flip format and concealed spiral make it easy to look up information, while tabs direct you to the right section. Think of this as flip cards in a book: every page is split into numbered segments; each one provides detailed answers to a particular question. Go right to the one that interests you--say, "primes and composites" or "types of equations"--and lift up that slice of the page to get simple, understandable definitions of everything that relates to the subject. Among the many topics: multiplying with decimals, writing percentages, systems of measurement, averages and statistics, types of curves, and lots, lots, more! Perfect for students, business people who need to do some calculations, or anyone needing a brush-up!
