     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 2 to 9 thereof, a new and improved math facts game apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the math facts game apparatus 10 of the instant invention essentially comprises a plurality of disc members 11 whose construction includes a disc side wall 12 of continuous configuration, with the disc having a first end wall 13 spaced from and parallel a disc second end wall 14, with each of the discs first and second end walls 13 and 14 depicted in the respective FIGS. 3 and 4 indicating the respective first and second end walls 13 and 14 to provide for each disc having contrasting numerical designations thereon. The disc members 11 accordingly define an outer housing shell 15, with the side wall 12 and the first and second spaced end walls 13 and 14 to thereby provide for a disc housing cavity 22, with the discs indicated in FIG. 5 having a weighted core 16 to effect a specific gravity greater than one of the disc member 11 to promote the sinking of each disc member within a pool &#34;P&#34;, as indicated in FIG. 6 to position the discs on the pool floor. In this manner, various mathematical problems are directed to individual players, and the individual players to provide for a solution to the problems are directed to retrieve a single or plurality of the disc members 11 from the pool floor, with the numerical designations on the first and second end walls to correspond to solution to random numerical problems directed. 
     A modified disc member construction 11a is indicated in the FIGS. 7-9 to be employed by a single or plurality of the disc members, such as employed in the FIG. 6. The modified disc member 11a includes a modified side wall 12a that is separable for access to contents within the outer housing shell 15, and more specifically to the disc housing cavity 22. A sealing ring 25 coextensively directed through the side wall 12a  provides for fluid-tight sealing relative to the housing cavity 22. 
     Weighting of the structure includes a first weighted ring portion 20 and a second weighted ring portion 21 mounted within the housing cavity 22 positioned in contiguous communication against respective first and second end walls 13 and 14 to provide for the specific gravity to be greater than one for the sinking of the discs relative to the pool floor, in a manner as indicated in FIG. 6. Further if required, the outer housing shell 15 may be formed of a dense material such as lead and the like to effect this specific gravity determination. Within the housing cavity 22 is a battery bracket 23 mounted between the first and second weighted ring portions 20 and 21 mounting a battery 24 in a replaceable manner. The battery 24 includes electrical communication to illumination bulb 27 mounted to an illumination bulb mounting bracket 26 that extends from the side wall 12a into the housing cavity 22 medially of the first and second end walls 13 and 14. A first transparent window 18 and a second transparent window 19 are formed within respective first and second end walls 13 and 14, with the bulb positioned between the windows 18 and 19. The first and second transparent windows 18 and 19 are of respective first and second numerical configurations, such as indicated in the FIGS. 3 and 4 and 7 and 9 for example. A first electrical wire 28 is in electrical communication between the battery 24 and the illumination bulb 27 and directed to a first bulb contact 29. A second bulb electrical spring contact plate 32 is mounted in electrical communication with a bulb 27 in spring-biased communication to a second bulb contact post 31 fixedly mounted within the cavity 22 to the second end wall 14, with a second electrical wire 30 directed from the second bulb contact post 31 to the battery 24. A suction cup 33 is mounted within the cavity 22 to the second floor in alignment with a push button cap 37. Between the suction cup 33 and the push button cap 37 is a slide post 34 slidably mounted within the housing 22, and more specifically within the illumination bulb mounting bracket 26 (see FIG. 9) and maintained in alignment relative to the bracket 26 preventing rotation relative to the bracket 26 by the use of a slide post groove 35 receiving a bulb mounting bracket rib 36. An L-shaped abutment arm 38 orthogonally mounted to the slide post between the mounting bracket 26 and the suction cup 33 is in biased abutment with the second bulb electrical spring contact plate 32 to displace the spring contact plate 32 when the suction cup 33 is in a convex configuration abutting the slide post 34. In this manner, the L-shaped abutment arm 38 engages the spring contact plate 32 to effect a spacing between the second bulb contact post 31 and the spring contact plate 32 to discontinue electrical communication to the bulb 27. Initially, the push button cap 37 is projected downwardly to effect temporary securement of the suction cup 33 to the second end wall 14 thereby displacing the abutment arm 38 relative to the spring contact plate 32 permitting illumination of the illumination bulb as the spring contact plate 32 is in communication with the second bulb contact post 31. The suction cup 33 subsequently releases relative to the second end wall 14 in a configuration as illustration in FIG. 8 to the second position from the first position when the spring contact plate 32 is in communication with the second bulb contact post 31. In the second position, the bulb ceases illumination. Illumination accordingly assists individuals in the retrieving of the disc relative to the pool floor, as well as providing for a time sequence permitting the individuals a predetermined time only to retrieve the discs, whereupon subsequently as the bulb extinguishes, the retrieving individual is no longer availed of that disc 11a in the solution of the aforenoted mathematical problem posed. 
     As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
