Math Pirate Memo 对比 20/20 Absolute Value 的使用情况和统计数据

A power learning aid combines Guides, Practice and Coaching Calculators to help students master absolute value equations and inequalities. Students learn quickly working with Practice and Coaching Calculators to review each step of the solution process. Equations such as : |x| = 4 |7 - x| = 8 3|2x - 5| = 7 2|3x - 4| = 3x + 7 Inequalities such as : |x| > 4 |5 - x| > 4 3|3x + 5| > 8 2|3x - 4| > 3x + 7 Guides additionally cover equations and inequalities such as : 2|x| = |4 - x| |x² - 5x| = 6 2|1 - x| - 2|2x + 3| > 3 Examples highlight and simplify algebra that students find hard.
