App Description

Have you forgotten most of your algebra? Algebra Touch refreshes your skills using techniques only possible on your iOS device.

Say you have x + 3 = 5. You can drag the 3 to the other side of the equation.

Enjoy the wonderful conceptual leaps of algebra, without getting bogged down by the tedium of traditional methods.

Drag to rearrange, tap to simplify, and draw lines to eliminate identical terms.

Distribute by sliding terms across the sum, and Factor them back out by dragging them together.

Easily switch between lessons and randomly-generated practice problems.

Create your own problems or edit current ones.

Current material covers:
Simplification, Like Terms, Commutativity, Order of Operations, Factorization, Prime Numbers, Elimination, Isolation, Variables, Basic Equations, Distribution, Factoring Out, Substitution, and 'More Advanced' mode.

Made possible with support from the Percepts and Concepts Laboratory of Indiana University, Bloomington, and the Cave Lab at the University of Richmond.

Research supported by the Institute of Education Sciences, U.S. Department of Education, through Grant R305A110060 University of Richmond.
