Mathematical reasoning is the ability to think about mathematical problems, namely by thinking logically about mathematical problems to get conclusions about problem solutions. There are several factors that can affect students' mathematical reasoning, including mathematical abilities. Dissimilarity of students' mathematical abilities allows for dissimilarity in their mathematical reasoning abilities. So, this research intends to describe students' mathematical reasoning abilities in solving social arithmetic problems based on dissimilarity in mathematical abilities. The purpose of this research was to describe qualitative data about the mathematical reasoning abilities of students with high, medium, or low abilities in solving social arithmetic problems. The instrument used was the Mathematical Ability Test to determine the three research subjects, followed by a Problem Solving Test to get qualitative data about students' mathematical reasoning abilities, then interviews to get deeper data that was not obtained through written tests. Thus, the research data were analyzed using mathematical reasoning indicators. From the result of data analysis, it was found that all students understood the problem well. Students with high and medium mathematical abilities are determining and implementing problem solving strategies properly, namely writing down the step for solving them correctly and making accurate conclusions by giving logical argumens at aech step of the solution. However, students with low mathematical abillities have difficulty in determining and implementing problem solving strategies because they do not understand the concept, thus writing the steps to solve the problems incorrectly and not giving accurate conclusions about the correctness of the solution. Keywords: mathematical reasoning, problem solving, mathematical abilities

Orientation mathematics are mathematical reasoning abilities. Reasoning is a process or activity is thought to draw the right conclusions based on some of the statements that have been proven or assumed to be true. Students require reasoning ability in solving mathematical problems that involve critical thinking, systematic, logical, and creative. Through the mathematical reasoning students can apply for the alleged then compile evidence, manipulation, and draw conclusions correctly and precisely of the problem or a math problem. Mathematical reasoning skills students are low is one of the fundamental problems in mathematics today. The low student learning outcomes are influenced by many factors, one of which is the use of teaching methods that are less effective and efficient cause unbalance cognitive abilities, affective, and psychomotor student. Learning methods commonly used by mathematics teachers are conventional teaching methods that rely on lectures and main tools blackboard so that students tend to be passive and less involved in the classroom. Conventional teaching methods do not provide the opportunity for students to think and can hamper students' mathematical reasoning abilities. One of the techniques taught are considered accommodative can attract students and increase the activity of thinking students are learning techniques probing prompting. Which is a technique of learning by the teacher presents a series of questions that are guiding and dug so that a process of thinking that links students' knowledge and experience with new knowledge that is being studied.
