A method for representing and solving algebraic equations that allows a user to view and solve algebraic equations through a novel user-interface. The user-interface includes a primary cog and a plurality of secondary cogs as parts of a gear system. The primary cog represents a range of outcomes for the gear system and contains a plurality of teeth that is quantitatively greater than a numerical constant of the algebraic equation; amongst the teeth is a target tooth that represents the numerical constant. Each of the secondary cogs represent a term of the algebraic equation and includes a coefficient and a variable. Each of the secondary cogs contains a number of teeth equal to the coefficient. The equation is solved by rotating the secondary cogs until the target tooth is aligned with a fixed pointer where rotation of the secondary cog represents a value input for the variable of a term.
