Hands-On Equations 2 is an educational app designed for iPhone users. This app is the perfect introduction to algebra for elementary and middle school students, as well as a helpful tool for high school students struggling with algebra. It builds upon the concepts taught in Level 1 of Hands-On Equations and teaches students how to solve equations involving the white pawn, blue pawn, and red cubes.

In Level 2, students learn that the white pawn, also known as "star," is an unknown like the blue pawn. The value of the white pawn is the opposite of the blue pawn. For example, if x = 3, star = -3. When the white pawn and the blue pawn occur together on the same side of the scale, they can be removed without affecting the balance, since their sum is zero.

The app provides a video introduction for each lesson, followed by two examples and ten exercises. It is crucial for students to watch the lesson video before attempting the examples and exercises. The video instruction ensures that students have a clear understanding of the concepts and can successfully solve algebraic equations.
