ABSTRACT

This research aims to explore the use of ethnomathematics in revealing mathematical representations and in the formulation of a calculation system used in the Marosok trading tradition by the Minangkabau tribe in West Sumatra. Ethnomathematics studies ideas in various cultural activities practiced by ethnic, social, or professional groups. The tradition involves nonverbal communication, such as shaking hands with ‘Marosok’ or touching covered fingers to obtain price agreements in trading livestock. Therefore, this study was conducted using qualitative approaches and the ethnographic method via field notes, unstructured interviews, and documentation studies. The findings showed that mathematical representations of finger symbols and gestures in the Marosok Tradition contain basic numbers. These include half, one, two, two and a half, three, four, five, etc. with functions, such as addition and subtraction, which are used to obtain other numbers needed in livestock trading transactions using specific formulas.

摘要

本研究旨在探索民族数学在揭示数学表示和制定西苏门答腊米南加保部落在Marosok贸易传统中使用的计算系统中的用途。民族数学研究民族、社会或专业团体在各种文化活动中的思想。传统涉及非语言交流，例如与“ Marosok ”握手或触摸覆盖的手指以获得交易牲畜的价格协议。因此，本研究是通过实地记录、非结构化访谈和文献研究，使用定性方法和民族志方法进行的。研究结果表明，Marosok中手指符号和手势的数学表示传统包含基本数字。这些包括半、一、二、二半、三、四、五等，具有加减等功能，用于使用特定公式获得牲畜交易交易中所需的其他数字。
