Here is a Maths trick that will totally stump you. Personally I would like to know who came up with this and why that person is not running this country.
Grab a calculator; you won't be able to do this one in your head.
1. Key in the first four digits of your telephone number. (Not the area code)
2. Multiply it by 80
3. Add one.
4. Multiply it by 250
5. Add to this the last four digits of your telephone number.
6. Add to this the last four digits of your telephone number again.
7. Subtract 250.
8. Divide the number by 2.
