Feed the robot any plate with the calculation on top into the upper slot and the robot will return it with the solution on top.

Print in this order to play already during printing the other parts:

• Math Robot
• 10x1 .. 10x10
• Plate box

Print hints:

• printed with 0.4 nozzle at 0.3mm layer height - no supports needed
• for more contrast you can change color during printing the plates
• for good playing and learning experience use different colors. 

Additional plates for learning additions/subtractions/divisions etc. can easily made. Design a 20x20x2mm plate, text is negative and 0.5mm deep, for best effect orient solution upside down on the bottom - happy remixing
