The results showed that students had misconceptions about the concept of open and closed sentences, the concept of linear equations and inequalities of one variable, students' initial concepts in algebraic calculations, misconceptions about the use of symbols and misconceptions of translation. Students' misconceptions are caused by the wrong initial concept of students, students' associative thinking and students' low interest in learning. Based on the analysis of research data shows that 27.19% of students have misconceptions, 44.74% of students do not know the concept, and 28.07% of students who understand the concept.
