20/20 Absolute Value app for iPhone and iPad

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.
