This worksheet takes a deep dive into how parentheses can alter the answer to a calculation or mathematical expression.
Section A consists of twenty mathematical statements that students must add brackets to in order to make true. As the section progresses, the questions get increasingly more difficult. Learners may have to try parentheses in a few locations to find the correct solution. The section provides a good opportunity to discuss what parts of the calculation inserting parenthese would have no impact on. Only one pair of brackets is needed in each case.
Next, in section B, students are faced with four calculations with numbers missing. Here, they are to add numbers to make the statement correct. Answers may vary.
