This worksheet takes a deep dive into how brackets can alter the answer to a calculation or mathematical expression; therefore helping pupils in their understanding of brackets when using the correct order of operations (formally known as BODMAS).

Section A consists of eight calculations that each have four possible answers listed. Students will choose the correct answer. For the first time in our order of operations collection, positive and negative integers are used. Calculations consist of all four operations, brackets and indices. However, students are only required to square numbers in any calculation involving indices.

Next, in section B, pupils are faced with ten mathematical statements that are not correct. Brackets must be added to each in order to make the statements true. Some calculations require two pairs of brackets.
