If you multiply the digits in each
number from 11 to 100 which product occurs most often and why?
Which numbers appear the least and
which numbers fail to appear at all?
|
|
Would you get
the same result if you looked at numbers between 100 and 200 or
201 and 301?
Can you predict? |
|
Make a list of
the 2 digit numbers that do not appear in the grid.
What is the connection between these numbers? |
|
|
|
|
|
How
many times will the product be 24 from 0 to 1000?
Investigate other numbers. |

Look at the numbers in the section taken
from a number square.
If you add the digits in the numbers
together what totals do you get?
What do you notice?
Can you spot any patterns?
Where are all the eights? |
