Simplifying Expressions and Distributing Terms

The video tutorial explains how to simplify algebraic expressions by clearing parentheses and combining like terms. It covers three expressions, demonstrating the distribution of numbers and handling of negative signs. The tutorial emphasizes the importance of combining like terms by adding or subtracting coefficients while keeping the variable part unchanged. Each expression is simplified step-by-step, highlighting the process of distribution and the careful handling of negative numbers.
