Algebraic Expressions
- A coefficient is a numerical value that multiplies a variable in an algebraic expression, often represented by a letter or symbol.
- The degree of a term refers to the exponent or power to which the variable is raised, indicating the number of times the variable is multiplied by itself.
Evaluating Expressions
- To evaluate an expression involving variables, substitute the given values of the variables into the expression, following the order of operations (PEMDAS: parentheses, exponents, multiplication and division, and addition and subtraction).
- Simplify the expression by combining any like terms, and perform any necessary calculations to arrive at the final result.
