Abstract: Identifying errors in algebra provide information on misconceptions in algebra. This information is importation for educators to plan for the interventions program. The study identified the errors done by pre-commerce students in algebra. Explanatory design method was utilized and qualitative data were gathered from pre-commerce students. An algebraic assignment and two tests were used as instruments to identify errors and similar errors were coded under same theme. Students were interview to clarify the method used in obtaining their answers. The study identified five types of common errors in algebra by the students. The types of error were conjoin error, misapplication of rules, misinterpretation of cancellation, misuse of distributive property and sign error. The five types of error were related to the misconception on deficiency of prerequisite facts and concepts of algebra, could not systematically apply mathematical rules due to lack of basic understanding of algebraic expressions, incomplete understandings of arithmetical concepts, could not transfer arithmetic understanding to algebraic context and incompetence in dealing with integers and sign.
