Here is an amusing trick to play on your friends.
Ask them to think of a number between 100 and and 1,000. Suggest it has three different digits and tell them not to reveal it to you.
Ask them to multiply it by nine.
Ask them to add the digits together. If there is more than one digit, repeat until only one digit remains.
The answer will always be 9!
Example: 123 x 9 = 1107
digits add up to 9
Example 999 x 9 = 8991
digits add up to 27
add these 2 + 7 = 9
This works for any positive number, even with decimals, so you could use a much longer number and impress them with your mental arithmetic while they use pen and paper.
Example Pi x 9 is 3.1415926535 x 9 = 28.2743338815
digits add up to 54, which add up to 9!
