Arthur Goodman

Lewis Hirsch

Authors Hirsch and Goodman clearly and carefully develop students' understanding of intermediate algebra concepts by using a unique spiral approach. This approach presents a topic at an elementary level and then returns to it at increasing levels of complexity. This gradual introduction builds student confidence while developing concepts, rules, and definitions. To complement this approach, the authors include a wealth of numerical and algebraic examples that reflect a wide variety of situations. These illustrative examples compare and contrast related ideas, helping students understand the sometimes subtle distinctions among various situations.

Understanding Intermediate Algebra

Lewis Hirsch and Arthur Goodman strongly believe that students can understand what they are learning in algebra and why. The authors meticulously explain why things are done in a certain way, illustrate how and why concepts are related and demonstrate how 'new' topics are actually new applications of concepts already learned. The authors introduce topics at an elementary level and return to them at increasing levels of complexity. Their gradual introduction of concepts, rules, and definitions through a wealth of illustrative examples - both numerical and algebraic - helps students compare and contrast related ideas and understand the sometimes subtle distinctions among a variety of situations. Through this learning this author team carefully prepares students to succeed in higher-level mathematics.

Helping students grasp the "why" of algebra through patient explanations, Hirsch and Goodman gradually build students' confidence without sacrificing rigor. To help students move beyond the "how" of algebra (computational proficiency) to the "why" (conceptual understanding), the authors introduce topics at an elementary level and return to them at increasing levels of complexity. Their gradual introduction of concepts, rules, and definitions through a wealth of illustrative examples-both numerical and algebraic-helps students compare and contrast related ideas and understand the sometimes-subtle distinctions among a wide variety of situations. This author team carefully prepares students to succeed in higher level mathematics.

Understanding Elementary Algebra with Geometry

Everyone knows it's important to exercise your body if you want to stay healthy. But what about the mind? If you don't use it, you'll lose it. And what better way to keep sharp than by stretching your noodle with crosswords? The problem with modern crosswords, though, is that you have to know a lot of esoteric information to solve them. Who can remember who sang what song in the 1970s, who the Cubs' second baseman was in 1985, or who was the Best Supporting Actress of 1991? By contrast, these puzzles, originally printed in the 1960s, emphasize vocabulary and classical knowledge, not trivia and minutiae. Perfect for older puzzle fans. So try these 72 crosswords presented with spiral binding and larger-than-usual type--so you won't have to strain your eyes to train your brain. 96 pages, 140 b/w illus., 8 x 10. Spiral-bound.

Crosswords to Keep You Sharp

This text focuses on understanding concepts rather than on presenting rote procedures, and blends the various topics and applications of contemporary precalculus. Graphical, algebraic and numeric perspectives are provided, offering a broad view of topics.
