摘要：The article analyzes the understanding of numerical expressions in primary and secon-dary schools. Algebraic education begins in primary school by numerical expressions calcula-tions and transformations tasks. Understanding of these tasks remains important later while doing any of expressions, equations and inequalities tasks. The numerical expressions errors made by students show learning difficulties and inadequate understanding of concepts. This article presents 120 I–VI classes students numerical expressions solutions mistakes qualitative continent analysis. It revealed such problems as misunderstanding ideas of positional decimal counting system, constructive learning of rules, the lack of practical experience in trans-formating numerical expressions. There are proposed possiblities to improve the situation by paying more attention to decimal structure and the positions of numbers in primary classes, mul-tipurpose numerical expressions analysis, the increasing of motivation to solving numerical ex-pressions.
