<P>PROBLEM TO BE SOLVED: To provide a figure learning device for learning a proper calculation method of a figure area in a manner of easy-to-understand and easy-to-see. <P>SOLUTION: In a display screen of a question polygon figure ABCDE which combines colored element figures ABC/ACE/ADE, an optional element figure ADE is selected and a display color [2:Blue] of a neighboring element figure ACE is specified to integrate with the element figure ADE. As the specified display color [2:Blue] corresponds to the display color [Blue] of the neighboring element figure ACE, the element figure ACE is determined as an integration target. Whether an integrated figure ACDE, which is obtained by integrating the specified element figure ADE and the integration target element figure ACE, is a figure with a area formula or not is determined based on a element figure database mapping each type of element figures to its area formula. The display color of the specified element figure ADE is changed to the specified display color [Blue], and the integrated figure ACDE (Blue) is displayed as a figure whose area can be integrally calculated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
