Description:
This app is a quick reference guide to the addition and subtraction of rational expressions and their reduction and simplification.

Rational expressions are also known as algebraic fractions.

The app covers the addition and subtraction of rational expressions such as

3(x - 2)/2 - (x + 1)/5
12/(x - 1) + 5/x
3/(x + 1) + 2x/(x² - 6x - 7).

The app covers the simplification of rational expressions such as

(x² + 6x + 8)/(x + 2)
(x² - 5x + 6)/(14 + 3x - 5x²)
(3x² - 9x)/(x⁴ - 81).

Reduction questions cover:

- Factoring out GCFs
- Factoring linear numerators/denominators
- Factoring quadratic numerators/denominators
- Canceling common factors

It's ideal for students as the menu design reinforces each problem solving step. Examples highlight and simplify algebra that students find hard.

Large crystal clear text and graphics make the app ideal for quick reference or a longer read.

Updated:
Multiplication and division added. A note on Rational Functions. Improved layout and minor bug fixes.
