Abstract

This research aims to analyze junior high school student?s error in solving mathematics test on fraction using Makhubele, Nkhoma, and Luneta?s error category. This research was conducted by giving individual written test (three question) in the fraction material. Participants in this study were 5 junior high school students who had studied fraction material in their school. Based on the results of data analysis, it was concluded that students in number 1 had 2 students who did err1 (slip) and 1 student who did err2 (conceptual error), in number 2 there was 1 student who did err3 (procedural error), and in number 3 there is 1 person who did err2 and 1 person who did err1.

Abstract

Graph theory is applied to study network structures in various disciplines, such as computer science and discrete mathematics. The combination of graphs and algebra has become a widely discussed topic in research within the fields of algebra and combinatorics. Research on group representations on graphs and topological indices has been extensively conducted, one such example is on the identity graph. A identity graph of a group $G$ which is an ordered pair $V(G)$ and $E(G)$, where all elements of $G$ serve as vertices, and two vertices $x,y \in G$ are adjacent if and only if $x*y=e$. This study proposes an alternative approach to calculating topological indices in the identity graph of the multiplicative group of integers modulo n.

Abstract

Assuming that G is a finite group and H is a subgroup of G, the graph known as the relative coprime graph of G with respect to H (denoted as Γ_(G,H)) has vertices corresponding to elements of G. Two distinct vertices x and y are adjacent by an edge if and only if (|x|,|y|)=1 and x or y belongs to H. This paper will focus on  finding the general formula for some topological indices of the relative coprime graph of a dihedral group. The study of topological indices in graph theory offers valuable insights into the structural properties of graphs. This study is conducted by reviewing many past literatures and then from there we infer a new result. The obtained outcomes will include measurements of distance, degree of vertex, and various topological indices such as the first Zagreb index, second Zagreb index, Wiener index, and Harary index that are associated with distance and degree of vertex.

Abstract

Power graph of a group G, represented by \Gamma_G, is a graph where the vertex set consists of the elements of G. Two distinct vertices a, b \in G are connected by an edge if and only if there exists a positive integer m such that a^m = b or b^m = a. This study explores the utilization of a new approach to compute the topological indices of power graph associated with dihedral group with n=p^k, p is primes and k \in \mathbb{Z}. Results obtained indicate that the topological indices calculated using new approach yield the same values as those obtained with the conventional approach.
