Concept: Adding Linear Expressions
Concept: Adding Linear Expressions is a Grade 7 math skill from Big Ideas Math, Course 2, covering Expressions and Equations. To add linear expressions, we remove parentheses and combine like terms. Like terms have the same variable with the same exponent. Explanation Adding linear expressions means combining terms that are alike. Variable terms with the same variable combine by adding their coefficients, and constant terms combine by regular addition. For example: Examples To simplify , we add the coefficients to get .
Key Concepts
To add linear expressions, we remove parentheses and combine like terms. Like terms have the same variable with the same exponent. For linear expressions, we combine constant terms together and variable terms with the same variable together. To add like terms, we add their numerical coefficients.
