Abstract
This study aims to see how the Cognitive Psychology of Students in terms of measuring Mathematical Problems in Algebraic Forms of Operations and how students work on Mathematical Problems in Algebraic Forms. observations made at SMP Tunas Pertiwi. The result of this research is cognitive psychology is the study of how people perceive, learn, remember, and think about information. With the ability to develop students who are expected to be able to foster good knowledge so that it can help student survival in the future. it can be ignored that every child has cognitive development and requires special attention from parents or clerics in the process of student development. formulas, (b) operating errors, namely errors in calculations, (c) errors due to carelessness, namely because students do not check the answers that have been done, and (d) data errors such as notation errors
