And here’s another one. I don’t know about you but I’ve seen this one quite a few times but I was never able to figure it out. I remember my brother asking me numbers all the time and actually figuring them out but never told me how to do it. I guess those days are gone. Here’s the complete trick explained.
Basically you ask a person to think or a number between 1 and 9, annex a 0 to it, add the initial thought number to that result, multiply this sum by 3, then by 11 and the by 3 again, ask the person for the last digit of that result and you will be able to tell the entire number he computed, clear enough?, well here’s an example:
This part is all done by the person you’re asking. You don’t know this numbers.
- 1: The person thinks of any number, for the example we’ll use 3.
- 2: Annex a 0 to it. It will result in 30.
- 3: Add the original number to it. 30 + 3 = 33
- 4: Multiply this result by 3. 33 * 3 = 99
- 5: Multiply this result by 11. 99 * 11 = 1089
- 6: Multiply this result by 3. 1089 * 3 = 3267
Ask for the last digit from that number, the person should tell you 7
Now using that 7 you can compute (tell) this entire number and the number he first though. Here’s how:
- Last digit: 7 (This is the number the person told you)
- Second digit: 9 – 7 = 2
- First digit: 2 + 1 = 3
- Third digit: 9 – 3 = 6
3 (First digit) 2 (Second digit) 6 (Third digit) 7 (Last digit) = 3267
