Look what trick I learned on Youtube! I will guess your age!
- Pick any number from 1 to 10.
- Multiply your choosen number by 2.
- Add 5 to your total.
- Multiply your new total by 50.
- If you have already had your birthday this year, add 1767.
If you have not had your birthday this year, add 1766.
- Subtract from your total the year which you were born (e.g. 2003).
Now your total should be a three digit number.
The first number of your total will be the number you chose at the beginning.
The remaining two numbers are your age.
I found this thing on Youtube, and I wanted to show you this math trick! Like this topic if you like this trick.
