The low mastery of the concepts of basic arithmetic operations in elementary school students is due to the low ability to understand concepts, numeracy skills and the ability to solve word problems. For this reason, teachers in elementary schools are expected to be able to explain the concepts of basic arithmetic operations correctly. However, in reality, there are still many students who do not understand the concepts of basic arithmetic operations because mathematics learning does not receive enough attention. The aim of the research was to describe mathematical reasoning abilities, concepts of basic arithmetic operations related to understanding the concept of counting skills in whole numbers and fractions. This research used a descriptive qualitative approach. The research subjects were 2nd semester students of PGSD FKIP UNTAN and PGSD STKIP Singkawang in the Basic Mathematics Course. The object of research was students' mathematical reasoning abilities. Data analysis techniques included stages of data reduction, data presentation, and drawing conclusions. The results of this research were that the average mathematical reasoning ability for basic arithmetic operations concepts is 78.8%, with ability level 0 being 1.3%, ability level I being 3.9%, ability level II being 42.1%, ability level III is 39.5% and ability level IV is 13.2%. Overall, students had not mastered the concepts of basic arithmetic operations. Students' difficulties in mastering the concepts of basic arithmetic operations were shown by several students' mistakes in solving problems
