ABSTRACT: Combinatorial methods are used to give specific mathematics, and the proof of combinatorial identities is the hot spot research of combinatorial mathematics. Binomial coefficients play an ...

If \(f(x) = x^2\), then \(-f(x) = -(x^2)\). This means that each of the \(y\) coordinates will have a sign change. So \(y = 4\) would become \(y = -4\), and \(y = -1 ...

Abstract: Attributed graph clustering is an unsupervised learning task that aims to partition various nodes of a graph into distinct groups. Existing approaches focus on devising diverse pretext tasks ...

This article aims to contribute to the theory of mathematics instruction by highlighting and analysing Leen Streefland's work as a teacher in a primary school. Core ideas of Streefland's are discussed ...

Four preservice elementary teachers were studied during a field-based mathematics methods course. The purpose of the study was to investigate the elements of mathematics teaching and learning the ...
