The Little Green Math Book: 30 Powerful Principles for Building Math and Numeracy Skills
LITTLE GREEN MATH BK
內容簡介
The Little Green Math Book reads like a collection of math recipes to help us blend problems, principles, and approaches in creating our own lineup of splendid math cuisine. The book's four chapters include: (1) Basic Numeracy Ingredients, (2) Wonderful Math Recipes, (3) Favorite Numeracy Dishes, and (4) Special Math Garnishments. Along with 30 of the most fundamental, recurring math principles and rules, readers will find a three-tier system to rate the difficulty level of all problems -- one chili ("mild"), two chilies ("hot"), and three chilies ("very hot"). Enjoy the benefits of your own self-paced math course: *Contains 120 all-star problems to help readers discover the secrets of basic math. *Develop a feel for how numbers behave and what makes math problems tick. *Learn to solve equations by translating math into words and thinking conceptually. *Watch for pitfalls when working with percentage increase and decrease. *Use simple math to solve "business" scenarios involving price, cost, volume, profit, and break-even, as well as how to calculate markup versus margin and efficiency. *Be able to glance at graphs and grasp their underlying meaning. *Understand correlation: weak or strong, positive or negative, linear or nonlinear. *Gain a newfound confidence with an increased competency with numbers.Author's bio: Brandon Royal is an award-winning writer whose educational authorship includes The Little Blue Reasoning Book, The Little Red Writing Book, The Little Gold Grammar Book, and The Little Purple Probability Book.
