Exploring Custom Tool for Algebra Discs

Basic Algebra Discs generated by Custom Tool (1 Dec completed)
Progress made on 2 Dec. Discs can be generated so that they are not overlapped in same position. Deleting last generated disc one by one, or reset to delete all discs are now possible. Added a simple drop down list to generate questions for student to answer using disc representation
Progress made between 3 to 5 Dec 2020 Alternative way of generating and removing buttons (combination of Javascript and Geogebra script) Deleting any selected disc one by one, or removal of all discs at once are now possible. Flipping any selected disc to the "opposite" state, ie, 1 to -1, -1 to 1, x to -x or -x to x is now possible
Above made possible thanks to forum help by rami titled "Button Command (ggb script or JS script) for action on selected objects)"
