App Store Description

A power learning aid combines Coaching Calculators, Practice and Guide to help students master linear inequalities.

The Coaching Calculators focus on one-step, two-step and multi-step linear inequalities as well as those containing parentheses, decimals and fractions :

one-step : x − 2 ≤ 3 , x/7 ≥ 2

two-step : 3x + 8 ≤ 20, 2 ≥ 5 − 6x

multi-step : 4 + 9x ≥ 2x − 18

parentheses : 2(3 − 4x) ≤ 2x + 9

decimals : 0.25x + 1.5 = 9.9 − 0.2x

fractions : (1/2)x − 5 ≥ 3x + 1/5

Practice focuses on all of the above as well as harder inequalities with parentheses and fractions :

10 − 3(2 − 3(x + 5)) = 2x + 9

(1/2)(2x − 5) ≥ 3x + 3/4

Students learn quickly as they work with Coaching Calculators and Practice to review each step of the solving process.

The Guide includes step-by-step worked examples that highlight key differences between solving linear inequalities and solving linear equations.
