Abstract

The purpose of the research is to investigate the knowledge of High School students in dealing with and resolving inequations with one unknown. In particular, we explore students' ability to "translate" from the verbal formulation into mathematical language and vice versa, as well as their functional ability to use the algebraic operations required to resolve inequations. A questionaire with inequations were provided to 25 students.  Quantitative and qualitative analysis of students' answers indicate their important diffiuclties in handling the above mathematical objects.
