Guess the age and no shoes

Description:
You can guess the age and the number one shoe size through mathematical calculations.


Procedure:

1. Call for a volunteer up on stage, give him a calculator.

2. Send him to type his age in the calculator (eg 16)

3. Multiply that number by 20 (16 x 20 = 320)

4. Add to today's date. For example today October 1, add the digits in points number 3 with number 1. (320 + 1 = 321)

5. Multiply these numbers by 5 (5 = 321 x 1605)

6. Add the number of shoe sizes. For example 40 (40 = 1605 + 1645)

7. Let him say the end result (in this example 1645). To determine the age and shoe size, subtract the number obtained at the point no 6 (1645 in this example) with 5 times the current date in point number 3 (5 x 1 = 5). In the example, from 1645 to 5 = 1640. The first two digits (16) shows the age of the volunteers, while the digits on the back (40) shows the number of shoe sizes.
