This research is a descriptive research with qualitative approach with data collection using questionnaire, test, and interview method. Data analysis uses descriptive analysis. The results reveal that each personality type is different in showing the process of mathematical communication. Guardian students show more symbolic communication, then logical, and verbal communication. Artist students show more verbal communication, then symbolic, and logical communication.
