Description

Have you forgotten most of your algebra? Algebra Touch will refresh your skills using touch-based techniques built from the ground up for your iPhone/iPad/iPod Touch.



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.



"With this app, the author has successfully made algebra beautiful. I really wish this app existed when I was studying algebra 25 years ago." - geekswithjuniors.com

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



Easily switch between lessons and randomly-generated practice problems.



Create your own sets of problems to work through in the equation editor, and have them appear on all of your devices with iCloud.



Current material covers:

Simplification, Like Terms, Commutativity, Order of Operations, Factorization, Prime Numbers, Elimination, Isolation, Variables, Basic Equations, Distribution, Factoring Out, Exponent Product Rule, and Exponent Quotient Rule.

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.
