A system uses objects that can be combined to learn mathematical operations. Operand objects illustrate a numerical operand and an associated set of possible numerical solutions to operations performed on the operand number. Operator objects illustrate an operation symbol and a numerical operator. When an operator object and an operand object are combined, a mathematical operation consisting of the operand, the operation symbol and the operator is illustrated, and a solution to the operation is illustrated. The operand objects also include a non-numerical representation of the value of the operand, and the operator objects also include a non-numerical representation of the value of the operator. When combined, the representation of the value of the operator, and the representation of the value of the operand cooperate to represent the value of the solution to the mathematical operation.
