Mathemagic: Extreme number Prediction
Effects: You can make a prediction as the sum of 5 lines just finished the first line written. Line numbers in row 1, 2, and 4 randomly written by someone else, while you write the numbers in the row-to-3 and 5
Procedure:
1. Ask a spectator to move forward and determine how many digits to be used in the game (ranging from 2 digits to infinity). For example, the audience chose 5-digit numbers. Tell me that you and the volunteers will play with the sum of 5 lines.
2. Have volunteers write the 5-digit random numbers. When finished, say that you are able to predict the results of the sum, although not all lines were written.
* How to make predictions *
-If the last digit in the first row is greater than 1, then subtract the last digit by 2, and write the number 2 in front of the first digit. For example, the 56,743 volunteers write your prediction for the 256,741
-If the last digit in the first row is smaller than 2, then subtract the last digit by 2, subtract the second digit from the back with 1, and write the number 2 in front of the first digit. Example, volunteers write 56,470, then the prediction was 256,468. If you volunteer to write 56,471, then the prediction was 256,469.
Write the results predicted and enter into an envelope.
3. Ask someone else to write another 5-digit number under the first row. Suppose the person to write 87,069.
4. Now, you would write numbers in the third row. What should you look at the numbers in the second row. You should write the numbers in the third row of digits when added together with the numbers in the second row of the result 9. For example, the second line number 87,069. Then in the third row you write 12930.
5. For more someone else to write a five-digit number in the fourth row. For example, 97,438 people were writing.
6. Tell them that you will write a 5 digit number in the fifth row (the last). The principle is the same, you should look at the numbers in the fourth row. You should write the numbers in the fifth row of digits when added together with the figures in the fourth row the results 9. For example, the second line numbers 97,438, then in the fifth line you write 02,561.
7. Ask other spectators line the five count sum. Let him write down the results, and open your prediction in the envelope. The result must be the same!
8. At the end of the game you can say, "There are 3 possibilities that allows me to make this prediction. The first possibility, I can count very quickly, whereas the second possibility is that I can predict the future. The third possibility, I can very quickly calculate and predict the future! "
