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…
