This study aimed to describe the types of misconceptions conducted by preservice elementary teachers (PGSD) students in integer operations. Misconceptions are classified into 3 types: 1) Careless Errors (Ca); 2) Concept errors (Co); 3) Careless errors and Concept errors (Ca and Co). The researcher presented 6 problems about of integer operation to 45 students of PGSD (preservice teachers for elementary school) students that were taking elementary mathematics subject. The results showed that 10% of students made Careless errors (Ca) misconceptions in integer addition and subtraction. The highest portion of the students, 53% performed Concept error (Co) in subtracting negative numbers. Another 9% showed Careless and Concept error (Ca and Co) misconception in subtraction of integers of the same sign (negative with negative or positive with positive).
