Me: Today I will reward you legerdemain alter any natural numbers to 9. Let anyone who can change the number from 20 to 9 by using a mathematical operation that is added, less, times, for or another. Who could?
You 1: I, 20 divided by 2 minus 1 to 9.
Me: Good, what one can in other ways?
You 2: I, 20 minus 11 to 9.
Me: You 2 are also true, well now I've got a number that is written in this paper (before I set up a paper and wrote down a number), without looking at the numbers listed in this envelope you can turn it into nine?
You 1.2: (in unison) can not.
Me: Okay, now we're back, have a piece of paper and write a number at will You, may be small or large number of important natural numbers. Remember understanding numbers and different number, 75 is the number that
consists of two numbers is the number 7 and number 5. 8 is a number that consists of one number is 8. (You prepare each piece of paper and write an original number at will)
Me: Try to follow the orders I have the following:
- Multiply the number that you wrote den 9. The result is a natural numbers, there is consists of 1 point, 2 digits, 3 digits, 4 digits and so on. If the results are numbers which more than one number then follow these steps, if the result is a number that consists of one number then you should stop. Understand?
You 1.2: Understand!
Me: To which still continues, note the last number that you get. Sum of numbers that make up these numbers. If the results are numbers which more than one number then follow these steps, if the result is a number that consists of one number then you should stop. (Example 567 = 5 +6 +7 = 18 = 1 +8 = 9)
I: For a still continue on until you get numbers that consist of one digit.
Me: I believe that you must stop counting when the last number is 9
I: How successfully do so 9?
You 1.2: Prok ... prok ... (Applause chuckle admiringly)
(The secret: The results from the multiplication 9 and the sum of angka2 by multiplying it will always produce 9)
