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

The Coaching Calculators focus on one-step, two-step and multi-step linear equations 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 equations 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 step by step Guide includes many worked examples that highlight and simplify algebra that students find hard.
