I've recently compiled the color balls and gem stones, then used them to calculate the dozenal math, want to share the multiplication tables with everyone.
The 2, 3, 4, 6 tables are relatively easier because of the arithmetic patterns. By connecting the numbers from x-axis, then y-axis, the multiplication products can be figured out from the sequential formula.
