The EMTeachline mathematics software modules are organized by subject. The program line EMTask provides a repository of math problems with answers and solutions and easy-to-use test preparation tools. The program line EMSolution supports all options of EMTask, and additionally, provides each solution step with related definition, formulation, rule, formula and theorem. The program line EMMentor is an interactive software for training problem-solving skills that offers a variety of interactive learning algorithms and a unique system of performance analysis with methodical feedbacks, and supports all options of EMSolution and EMTask. The low-priced short version of each module differs in a number of included math problems.
