We can't say enough about the Algebra Explained apps!!! Variables can be tricky, but with the help of this application you can understand them - in no time! It goes over how to solve equations, with practice problems and videos every step of the way, making a potentially befuddling subject very real. In addition, this app reviews the two earlier chapters, Order of Operations and Negative Numbers! I have seen the first hand results from the Algebra Explained apps and just have to say, they nailed it!
This is the third in a series of Algebra Explained apps. To get a complete understanding, one should take the time to go through all of them!
Compatible with iPhone, iPod touch, and iPad.
