ABSTRACT:
In one embodiment, the musical box includes a box-like support structure and a music device disposed in the interior of the structure. A plurality of flexible continuous webs are sized to wrap around the outside of the structure. Each web has, along its outside surface, indicia representative of a particular mathematical data table, such as a multiplication table. One column of the table indicates the mathematical resultant of the remaining laterally displayed data. The resultant is disposed proximate a side of the support structure. A controllably movable strip or continuous web has a window and the window is sized to reveal one mathematical resultant. This continuous windowed web is driven by a gear and knob actuator.
