## Simplifying Expressions

Summary
The essence of simplifying algebraic expressions lies in understanding and applying the fundamental principles of combining like terms and manipulating parentheses.
• Combining like terms involves adding or subtracting terms with the same variable parts, which is a cornerstone of algebraic simplification.
• The distributive law allows for the simplification of expressions by grouping like terms, which can significantly streamline complex algebraic expressions.
• Multiplication is commutative, meaning the order of factors does not affect the product, allowing for flexibility in identifying like terms.
• When dealing with parentheses, removing them involves either directly erasing them in the case of addition or changing each term to its opposite sign in the case of subtraction.
• Practical exercises in simplifying algebraic expressions underscore the importance of these concepts and provide a foundation for more advanced algebraic manipulation.
