The listing, Advanced Math Equation Dice (Qty: 12) has ended.
This listing is for 4 sets with 3 dice each. They feature mathematical equations instead of the actual 1-6 numbers (though the answers to the equations will be 1,2,3,4,5,6)
These are pretty tough, but great educational tools and/or conversation starters! Each set has a red, green, and blue die. All 4 sets are the same, but that is still 18 different equations.
Note: One mathematician claims one side of these dice is actually wrong. Others disagree. Why not check it out for yourself?
