Domino multiplications


You have a set of 27 domino tiles (the 0-0 tile has been removed).
Use any three tiles to show a mathematical multiplication. No leading zeros (zeros on the left) are allowed.
 

Example: 24 x 5 = 120

If you don't have domino tiles to play with, print the page and cut out the tiles below or make little drawings to assist you infinding the a solutions.

Write your solution as follows (top tile, vertical tile with top number first, left tile) and e-mail to your lecturer.

 
   
2-4, 5-0, 1-2
