Algebraic Representation of the Envelope and Counter Model
When translating the envelope and counter model into an algebraic equation, each component of the physical workspace corresponds directly to a mathematical concept. The contents of the envelope represent the unknown quantity and are typically denoted by a variable, such as . The collection of envelopes and counters on each side of the workspace forms an algebraic expression. The center dividing line of the workspace takes the place of the equal sign, establishing that the expressions on the left and right sides are equivalent in value. For instance, an envelope and three counters on the left, with eight counters on the right, translates directly to the equation .
