The purpose of this study is to describe the misconceptions experienced by students in linear combination material. This study is a qualitative descriptive study with a snowball sampling technique by taking 1 subject who experienced misconception in linear combination. The triangulation used in this study is technique triangulation which is a test in the form of description and interview. The result of this study shows that the subject experiences misconception in linear combination which is in the forming process of coefficient matrix. The subject immediately assumes that the coefficients of each polynomial are known as row vectors in coefficient matrix, regardless of its scalar multiplier. This indicates that the subject is too early to resolve linear equation system in which it should be multiplied first by its scalar. Based on this finding, it can be used as an input for development research of textbook whose its teaching material emphasizes certain material, such as linear combination.

Abstract: The theory distinguishes human based on four different personality types such as: sanguine, choleric, melancholic, and phlegmatic. Different types of personality caused by differences in the dominant fluid in the body. These differences will result in terms of behavior, ways of thinking and to get along. The type of this research that is descriptive qualitative which it is describing the logical reasoning based on Hippocrates personality types. The logical reasoning is analyzed through the four types of personality in relation to mathematical problem solving. The Analysis is done based on the logical reasoning indicator/ subindicator and the steps of problem solving stated by Polya. The result shows that there is a reasoning difference on each type of personalities. The difference can be terms of the strenght or the weakness. Sanguine is quicker in understanding problems and communicating results, choleric is more accelerated in work, melancholic is more perfect at work, and  phlegmatic is superior in terms of accuracy. Keywords: Logical reasoning, Hippocrates, sanguine, choleric, melancholic, phlegmatic
