Task

Watch Out for Parentheses 1

Illustrative MathematicsVaries

This problem asks the student to evaluate six numerical expressions that contain the same integers and operations yet have differing results due to placement of parentheses. It helps students see the purpose of using parentheses. Asking if the parentheses could be removed points out that sometimes we use parentheses to emphasize the grouping of numbers only. In this case, the parentheses can be removed without changing the value of the expression.
