The present study focused on the lack of knowledge of the double use of brackets in arithmetic expressions and the difficulty in the operatively of expression for mathematics application at the school level. Learning the other rules and formulas of mathematics involves learning the use of a bracket. Binding is useful in both arithmetic and algebra. If the bracket is not used properly, the value of the mathematical result is completely changed. The concept of this bracket is inserted into the students while learning school-based mathematics. So at the beginning of the bracket learning process, school-based textbooks, curriculum, and teachers are of great importance. The methodology of the proposed study is based on the document-based analysis. This study employed including studying international and national journals, library consultation, expert opinion, online journals, periodical, newspapers, and documents. Finally, the researcher suggested the importance, precaution, and effectiveness of using brackets in arithmetic
