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

I’ve been looking at some maths this morning and came across this one. No matter what number you choose to start playing you will always get back to the same number: 7

Follow this steps and have fun:

- 1: Think of any number you like, we’ll use 12 for the example.
- 2: Double your number, in our case it will be 24.
- 3: Add 14 your doubled number, we’ll get 38.
- 4: Divide your number by 2. Our result is 19.
- 5: Finally, subtract you original number from your result, in our case that number was 12.

19 – 12 = 7

And there you go, always back to the 7
