NEVER GET CRUNCHED BY NUMBERS AGAIN. Even in a world where every cell phone is also a calculator, basic math competency is a must! In this book, you'll learn how to efficiently solve common problems and effortlessly perform foundational math operations like addition, subtraction, multiplication, and division. Once you've got that down, we'll go over how to handle the scary stuff—like exponents, square roots, geometry, and algebra. Our user-friendly techniques break complicated problems down into their basic parts, so that you don't waste your time memorizing dozens of long formulas and equations. THIS THIRD EDITION INCLUDES: · Back-to-basics reviews of numbers, fractions, ratios & proportions, exponents & roots, algebra, geometry, and probability & statistics · Comprehensive reviews for solving problems in common math topics · Targeted strategies to help you score higher on the quantitative sections of the SAT, ACT, GRE, and GMAT · Access to additional challenging drill questions online · Key math terms lists at the end of each chapter
Whether you're checking out at the supermarket or cashing in at the stock market, you need a command of basic math to survive in today's number crunching world. But most people have problems with math. A decimal here and an exponent there and you've gone from a balanced checkbook to a multi-trillion-dollar national debt. That's why The Princeton Review created Math Smart. Math Smart's approach is easy to follow. We'll show you how to perform basic math operations like addition, subtraction, multiplication, and division. Once you've got that down, Math Smart will teach you how to handle the scary stuff like exponents, square roots, geometry, and algebra. How does Math Smart work? It teaches you user-friendly techniques that break down complicated problems and equations into their basic parts. You won't waste your time memorizing dozens of long formulas and equations. We don't promise you'll love math, but after reading Math Smart, you'll never be crunched by numbers again.
Make Rich Math Instruction Come to Life Online In an age when distance learning has become part of the "new normal," educators know that rich remote math teaching involves more than direct instruction, online videos, and endless practice problems on virtual worksheets. Using both personal experience and those of teachers in real K-12 online classrooms, distance learning mathematics veteran Theresa Wills translates all we know about research-based, equitable, rigorous face-to-face mathematics instruction into an online venue. This powerful guide equips math teachers to: Build students’ agency, identity, and strong math communities Promote mathematical thinking, collaboration, and discourse Incorporate rich mathematics tasks and assign meaningful homework and practice Facilitate engaging online math instruction using virtual manipulatives and other concrete learning tools Recognize and address equity and inclusion challenges associated with distance learning Assess mathematics learning from a distance With examples across the grades, links to tutorials and templates, and space to reflect and plan, Teaching Math at a Distance offers the support, clarity, and inspiration needed to guide teachers through teaching math remotely without sacrificing deep learning and academic growth.
This book guides you through pre-algebra, algebra, and geometry -- the fundamental concepts you're striving to conquer, or the ones you once learned but may have forgotten -- in just 20 easy steps.

From calculating monthly mortgage payments to the time you’ll need to pay off a credit card, this book walks you through the steps to understanding basic math concepts. This latest edition is updated to reflect recent changes in interest rates, prices, and wages, and incorporates information on the intelligent and efficient use of calculators and mental math techniques. It also offers: A brand-new chapter on hands-on statistics to help readers understand common graphs An easy-to-use-format that provides an interactive method with frequent questions, problems, and self-tests Complete explanations of necessary mathematical concepts that explore not just how math works, but also why it works Perfect for anyone seeking to make practical use of essential math concepts and strategies in their day-to-day life, All the Math You’ll Ever Need is an invaluable addition to the libraries of students who want a bit of extra help applying math in the real world.
“Witty, compelling, and just plain fun to read . . ." —Evelyn Lamb, Scientific American The Freakonomics of math—a math-world superstar unveils the hidden beauty and logic of the world and puts its power in our hands The math we learn in school can seem like a dull set of rules, laid down by the ancients and not to be questioned. In How Not to Be Wrong, Jordan Ellenberg shows us how terribly limiting this view is: Math isn’t confined to abstract incidents that never occur in real life, but rather touches everything we do—the whole world is shot through with it. Math allows us to see the hidden structures underneath the messy and chaotic surface of our world. It’s a science of not being wrong, hammered out by centuries of hard work and argument. Armed with the tools of mathematics, we can see through to the true meaning of information we take for granted: How early should you get to the airport? What does “public opinion” really represent? Why do tall parents have shorter children? Who really won Florida in 2000? And how likely are you, really, to develop cancer? How Not to Be Wrong presents the surprising revelations behind all of these questions and many more, using the mathematician’s method of analyzing life and exposing the hard-won insights of the academic community to the layman—minus the jargon. Ellenberg chases mathematical threads through a vast range of time and space, from the everyday to the cosmic, encountering, among other things, baseball, Reaganomics, daring lottery schemes, Voltaire, the replicability crisis in psychology, Italian Renaissance painting, artificial languages, the development of non-Euclidean geometry, the coming obesity apocalypse, Antonin Scalia’s views on crime and punishment, the psychology of slime molds, what Facebook can and can’t figure out about you, and the existence of God. Ellenberg pulls from history as well as from the latest theoretical developments to provide those not trained in math with the knowledge they need. Math, as Ellenberg says, is “an atomic-powered prosthesis that you attach to your common sense, vastly multiplying its reach and strength.” With the tools of mathematics in hand, you can understand the world in a deeper, more meaningful way. How Not to Be Wrong will show you how.
