Mathematics teaching system
First Claim
1. A mathematics teaching system for use by a student, for performing operations involved in calculation comprising:
- entry means operable by said student to enter a mathematics problem and a step-by-step solution of said problem;
calculating means for automatically calculating a correct step-by-step solution to said problem; and
display means, said calculating means providing carry and borrow information to assist the student in performing calculations required in calculating said step-by-step solution of said problem, said display means being responsive to said entry means to display the entered calculation steps and being responsive to said calculating means to display said carry and borrow information to assist said student in performing calculations required in calculating said step-by-step solution.

Abstract
A mathematics teaching system comprises a keyboard, for entering an arithmetic problem to be solved and includes display elements to display said problem and a solution thereto. Electronic components automatically calculate the correct step-by-step solution and provide carry-borrow information to assist the student in making his calculations and performing a step-ty-step solution. Electronic circitry and components compare the calculated step-by-step solution with each step entered by the student and generate a "try again" signal upon entry of an incorrect step by the student. Equipment operable by the student is provided to erase an incorrect step. The system can be set to operate in a manual mode comprising a step-by-step solution by the student or one of two automatic modes, one of the latter comprising the displayed solution upon the entering of the problem and the second comprising the displayed step-by-step solution upon entry of a signal by the student.

30. A mathematics teaching system operable by a student comprising:
-
entry means for entering an arithmetic problem and for entering a step-by-step solution to said problem; calculating means for automatically calculating a correct step-by-step solution to said problem; comparison means for comparing the correct calculated step-by-step solution to the step-by-step solution calculated by the student and for generating a signal indicating error when a calculation step entered by the student differs from the correct calculated step-by-step solution, said calculating means providing carry-borrow information to assist the student in making each calculation step in performing the calculation of the step-by-step solution to the problem; and display means comprising a screen of a television receiver, said display means being coupled to said means for entering an arithmetic problem, said calculation means, said entry means and said comparison means such that said display means is actuated to display said arithmetic problem, said entry of said calculation steps by the student, said borrow-carry information and said signal indicating a variance between the correct calculated step-by-step solution and an incorrect calculation step by the student. - View Dependent Claims (31, 32, 33, 34)
