The content is interactive and helps in learning addition of algebraic expressions. It consists of following levels: Level 1. Prove the identity (a + b)2 = a2 + b2 + 2ab  algebraically.
Level 2. Use the identity (a + b)2 = a2 + b2 + 2ab  to square binomials.
Level 1. Prove the identity (a - b)2 = a2 + b2 - 2ab  algebraically.
Level 2. Use the identity (a - b)2 = a2 + b2 - 2ab  to square binomials.
