   Teal Box   MediumVioletRed Box   SpringGreen Box   MediumBlue Box   DarkOliveGreen Box   Gold Box   LimeGreen Box   GreenYellow Box   Chocolate Box  times     Black Box Box  equals     CornflowerBlue Box   Teal Box   MediumVioletRed Box   SpringGreen Box   MediumBlue Box   DarkOliveGreen Box   Gold Box   LimeGreen Box   GreenYellow Box

We start with nine boxes, multiply by one box, and now still have nine boxes.


Here's another example:

   MediumSlateBlue Box   Sienna Box   Maroon Box   DarkBlue Box   Tan Box   DodgerBlue Box   Chartreuse Box   Coral Box   MidnightBlue Box  times     Black Box Box   Black Box Box  equals     MediumSlateBlue Box   Sienna Box   Maroon Box   DarkBlue Box   Tan Box   DodgerBlue Box   Chartreuse Box   Coral Box   MidnightBlue Box   MediumSlateBlue Box   Sienna Box   Maroon Box   DarkBlue Box   Tan Box   DodgerBlue Box   Chartreuse Box   Coral Box   MidnightBlue Box

We start with nine boxes, multiply by two boxes, and now have eighteen boxes. We take our nine boxes two times to get eighteen boxes:

                  

                  

   MediumSlateBlue Box   Sienna Box   Maroon Box   DarkBlue Box   Tan Box   DodgerBlue Box   Chartreuse Box   Coral Box   MidnightBlue Box    MediumSlateBlue Box   Sienna Box   Maroon Box   DarkBlue Box   Tan Box   DodgerBlue Box   Chartreuse Box   Coral Box   MidnightBlue Box

We start with nine boxes, multiply by three boxes, and now have twenty-seven boxes. We take our nine boxes three times to get twenty-seven boxes:
