A power learning aid combining Coaching Calculators and Guides to help students master the solving of linear equations.
Coaching Calculators focus on one-step, two-step and multi-step equations such as x + 6 = 9, x/2 - 5 = 6 and 5x + 2 = 3x + 8 respectively.
Students learn quickly as they work with the Coaching Calculator to review each step of the process in detail.
The step by step guide includes many worked examples that highlight and simplify algebra that students find hard.
One-step
x - 2 = 3, 5 + x = 4, 3x = -12, x/7 = 2
Two-step
3x + 8 = 20, x/9 + 2 = 5
Multi-step
4 + 9x = 2x + 18
Equations with parentheses
10 - 3(2 - 3x) = 2(x + 9)
Equations with fractions
(5/6)x - (3/4)x = 7/3
Equations with decimals
0.25x = 9.9 - 0.2x
The Guide also looks at Cross Multiplication as a useful shortcut.
