<p><P>PROBLEM TO BE SOLVED: To provide information concerning a solution in a test and learning utilizing an information terminal device or the like. <P>SOLUTION: A server system 300 transmits problem data to a multi-functional function calculator 100 connected with a network, and answer data is received from the multi-functional function calculator 100. The server system 300 determines correction of errors of the received answer data, and answer contents of the answer data which are determined whether correct or wrong in which contents are different are stored as solution data. The answer data are prepared on the basis of the solution data, and the solution data and the answer data are transmitted to the multi-functional function calculator 100. The multi-functional function calculator 100 designates the solution data corresponding to the answer data from the received solution data to display the solution data. <P>COPYRIGHT: (C)2004,JPO</p> |
