Abstract: A major problem in algebra education concerns the relationship of students with algebraic language, namely with the construction, interpretation and transformation of algebraic expressions and propositions containing numbers and letters. In this article, we describe the algebraic line component and the algebraic manipulator component of ALgebra on NUmerical SETs, a system designed and implemented to improve the relationship between students and algebraic language.
Keywords: algebra of operations; algebra of quantities; ALNUSET; numerical sets; algebraic line; algebraic manipulator; equations; expressions; inequations; learning algebra; polynomial roots; propositions; teaching algebra; teaching mathematics; mathematics education; algebraic language.
