- A 'jiffy' is an actual unit of time for 1/100th of a second.
- 1 and 2 are the only numbers where they are the values of the numbers of factors they have.
- 'Forty' is the only number that has all its letters in alphabetical order.
- 'FOUR' is the only number in the English language that is spelt with the same number of letters as the number itself
- Multiply 37,037 by any single number (1-9), then multiply that number by 3. Every digit in the answer will be the same as that first single number.
- 1x9 +2 = 11 , 12x9 +3 = 111 , 123x9+4 = 1111 etc
