Dy/dan. The mathematics I encounter in classrooms. Overthinking my teaching. The way I see it, there are two types of systems of linear equations problems: Those in which each equation represents a function relationship between two dynamic variables. We will call these racing problems, andThose in which each equation represents partial information about two or more static relationships and we seek to infer information from the system.
