Alef: algebra

I'm one of the creators of this app. Alef allows users to play with equations before they know (or after they forget!) the rules of algebra. Enter any expression and solve it using familiar drag-and-drop gestures. Forget how to solve an equation? Just start dragging and let Alef guide you. Great for students, teachers, and anybody who occasionally needs to solve an equation. We would love your feedback so post your comments below. You can download Alef now on your tablet or phone: iOS: https://itunes.apple.com/us/app/... Android: https://play.google.com/store/ap...
