The conscious or unconscious entry of mathematics into various aspects of life is certainly interesting to study such as from a cultural point of view. What can bridge the gap between culture and mathematics is ethnomathematics. Ethnomathematics is a study of the relationship between mathematics and culture. The study of mathematics in culture needs to be developed further to be able to provide an overview to the public about the role of mathematics in culture. one of the tribes that is rich in culture is Toraja, for example in Toraja carving which is a cultural heritage that is passed down from generation to generation until now there is the concept of geometry. Therefore, the purpose of this research is how the concept of geometry in Toraja carving using qualitative research methods ethnographic approach.

This literature aims to present the integration of TPACK (Technological, Pedagogical, And Content Knowledge) in mathematics learning and see its role in increasing learning effectiveness. By conducting analysis from various relevant sources of articles, journals and previous research, we can identify the benefits of integrating TPACK in mathematics learning in algebra form material. The results of this literature analysis show that there is a positive impact in increasing the effectiveness and abilities of students. The combination of technology, pedagogy and content knowledge makes mathematics learning able to provide a more interactive learning experience. It is hoped that this article can be a helpful reference for educators and educational researchers who are interested in implementing TPACK in the learning process to increase learning effectiveness.
 
 

This study aims to gather sufficient information about the sexagesimal base 60 number system. This research method is a literature study that collects some previous studies to answer about the sexagesimal base 60 number system. The results of this research show that the sexagesimal or sixtieth number system is the same calculation as Babylonian people's astronomical calculations, in their use sexagesimals can be said to be easier to use than decimal numbers, and to this day the sexagesimal number system is still used in a modified form to measure time, angles, geographic coordinates, and is still used in the field of astronomy.
