This thesis discusses the inverse and general inverse of a trapezoidal fuzzy number matrix. Suppose u = (a, b, α, β) an arbitrary trapezoidal fuzzy number which is converted into fuzzy intervals to determine the mean or m(u) of the fuzzy number. The middle value is used to construct the arithmetic of multipli- Furthermore, the constructed arithmetic is used to determine the inverse of the …
The independent curriculum requires students to have mathematical problem solving abilities (KPMM) as a skill needed to overcome the situations they face. The aim of this research is to create a teaching module that addresses students' low KPMM, particularly their lack of understanding of basic mathematical concepts, difficulty in understanding problems, and inability to apply appropriate formu…
the purpose of this research is to design Student Worksheets (LKPD) for mathematics on Relations and Functions for eighth-grade students by implementing Problem-Based Learning (PBL) model. The development method applied is through the 4D model, which includes the define (definition), design, development, and disseminate phases. Research instruments involve validation sheets for LKPD and student…

Angle trisectors are basically for Morley’s Theorem, which is about the exis- tence of equilateral triangles formed from the intersection of trisectors. This angle trisector has been developed by several authors on the convex quadrilate- ral with the result in the form of a comparison of the area of the shape formed from the angle trisector. In addition to area comparisons on angle trisectors…
This research aims to produce LKPD based on the Realistic Mathematics Education Approach (PMR) Circle content to facilitate valid and practical mathematical critical thinking skills of SMP/MTs students. The research method used was research and development (R&D) with a 4-D model (four D models). This research involved 3 validators, in the one to one evaluation trial involving 3 students, in the…
This research is based on the importance of students communicate mathematically ability. The limited ability of students to communicate mathematically in the topic of Circles is due to the learning model used not yet facilitating students' mathematical communication skills. This study aims to produce mathematical learning tools in the form of syllabus, RPP, and LAS using the Reciprocal Teaching…
