Understanding Backtracking in Algebra

The video tutorial introduces backtracking as a method to understand algebra, primarily used in years 7 and 8. It explains the concept through three examples, demonstrating how to solve equations by performing operations and then reversing them. The tutorial emphasizes the importance of understanding the order of operations and using brackets correctly. It concludes with tips and encourages students to ask questions if needed.
