Subtracting Linear Expressions

The video tutorial explains how to simplify linear expressions by subtracting groups using both vertical and horizontal methods. It emphasizes the importance of distributing the negative sign and aligning like terms. The instructor demonstrates both methods with examples, highlighting the benefits of each approach. The video concludes with encouragement to practice and apply these methods.
