What patterns do you see in them?
Suppose you have to share 9872 gold coins between 8 people.
You give the coins out in thousands until there are less than 8000 left.
Then you give out one hundred at a time until there are less than 800, then 10 at a time then 1 at a time.
You could do this sharing by splitting the coins into 4 piles and sharing each of the piles between the 8 people.
You give each person 1000 + 200 + 30 + 4 coins.
9872 ÷ 8 = 1000 + 200 + 30 + 4 = 1234
Using the subtraction calculations that you have already done can you complete all of these calculations without using a calculator?
What patterns do you notice? Why do you think that the ancient Egyptians called these numbers magic numbers?
