Abstract

This study aims to describe students' mistakes in completing algebraic form operation questions based on Newman's stages. This research approach is a qualitative approach using descriptive research types. Data collection techniques were carried out by test and interview methods. The validity test of the data is done by source triangulation. The results showed that the mistakes made by students were a reading error of 44.4%, understanding the problem of 72.2%, transformation of 44.4%, process skills of 44.4%, and answer writing of 77.8%. The cause of students' mistakes is because they cannot mention the keywords or symbols on the questions, students do not understand the problems that exist in the questions, students do not write down the procedures used, make mistakes in calculations so that the final answers are wrong, and errors in writing units.
