#2: May I have a large container of coffee, madam. This gives 3.14159265, Pi to 9 digits. As to #5, I tried 2 different 2-digit numbers 6 times, and couldn't get anywhere near the results that were suggested.

Number seven should be multiply first digit by itself, then add the first digit to that product and then put 25 at the end. For example, 45*45=2,025, 4*4=16+4=20, add 25 to the end and you get 2,025. It works every time!

Also - to represent pi (3.14159265) as a fraction instead of 22/7 which works out as 3.1428571 correct to only 2 decimals - try 355/113 = 3.14159292 correct to within 3 parts per 10 million!

Since I once got 0/100 in a maths exam and had to have special coaching to get through what was then known in the UK as "O" levels all of this was way beyond me

Example #6 makes me think of what you can do with multiples of 9.
