Algebraic Expressions Chart
Understanding algebraic expressions is crucial in mathematics, as they involve variables, constants, and operations. Here is a chart to help you better grasp algebraic expressions:

Types of Expressions
- Variable: A symbol that represents a number or value, such as x or y.
- Constant: A number on its own, like 5 or -3.
- Term: A combination of variables and constants, separated by an operation.
- Coefficient: The number in front of a variable in a term.
- Like Terms: Terms that have the same variables raised to the same power.

Common Operations
- Addition: Combining like terms by adding their coefficients.
- Subtraction: Subtracting coefficients of like terms.
- Multiplication: Multiplying coefficients and combining variables.
- Division: Dividing coefficients and simplifying the expression.

Examples of Algebraic Expressions
- 3x + 2y: This expression has two terms, 3x and 2y, with coefficients 3 and 2 respectively.
- 5x^2 - 4xy + 7: This expression includes three terms, with variables raised to different powers.

Rules for Simplifying Expressions
- Combine like terms: Add or subtract coefficients of terms with the same variables.
- Apply distributive property: Multiply terms inside parentheses by the term outside.
By understanding these key components and operations, you can effectively work with algebraic expressions and solve complex mathematical problems.
