Work out these subtractions.

What patterns do you see in them?

Suppose you have to share 9872 gold coins between 8 people.

You split them into 4 piles. Then you share each of the piles between the 8 people

You give each person 1000 + 200 + 30 + 4 coins.

Use the coin sharing story to explain the division sum:

9872 ÷ 8 = 1000 + 200 + 30 + 4 = 1234

The brackets in these calculations tell you that you must do the calculation inside the brackets first.

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?
