Error Analysis, Mixed Operations, IntegersAbstract
This study aims to determine the errors students make in solving mixed arithmetic operations of whole numbers at SMP Negeri 2 Kubung based on Newman's error analysis. This type of research is descriptive qualitative research. Based on the results of student work on mixed integer arithmetic test questions number 1 to 4, researchers found student errors in understanding the basic concepts of mixed arithmetic operations and the basic concepts of positive and negative numbers, then errors in transformation, then errors in process skills, then errors in writing the final answer. This study concludes that reading errors occur because students misread numbers, number signs, and signs of times, divides, adds, and subtracts found during interviews. Errors in understanding the problem happened because students' understanding of the concepts of positive and negative numbers and the basic concepts of mixed arithmetic operations had yet to be perfectly mastered by students. Transformation errors occurred because students incorrectly determined the transformation of arithmetic operations. Process skill errors occurred because students incorrectly determined the order of mixed arithmetic operations in the test questions. Errors in writing the final answer occurred because students were wrong in counting and did not put a number sign on the results of the calculation operations done.
