摘要：
Introduction. This study aimed to investigate the errors made by 265 Form 2 male students in simplifying algebraic expressions. Method. A total of 265 Form 2 (Grade 7) male students were selected for this study. 10 high, medium and low ability students in each group were selected for the interviews. 40 items were administered to the respondents to investigate their errors in simplifying algebraic expressions. Results. This study identified 12 types of errors. A comparison of the types of errors exhibited by high, medium and low ability students was investigated. Conclusion. All these errors might be the results of: (i) interference from new learning; (ii) difficulty in operating with the negative integers; (iii) misconceptions of algebraic expressions; and (iv) misapplication of rules.
