IN.6.3. Algebra and Functions
Students write verbal expressions and sentences as algebraic expressions and equations. They evaluate algebraic expressions, solve simple linear equations, and graph and interpret their results. They investigate geometric relationships and describe them algebraically.
6.3.3 Interpret and evaluate mathematical expressions that use grouping symbols such as parentheses.
6.3.4 Use parentheses to indicate which operation to perform first when writing expressions containing more than two terms and different operations.
6.3.6 Apply the correct order of operations and the properties of real numbers (e.g., identity, inverse, commutative, associative, and distributive properties) to evaluate numerical expressions. Justify each step in the process.
