1. First of all, pick a number between 1 and 7
2. Multiply this number by 2 (just to be bold)
3. Add 5
4. Multiply it by 50 -- I'll wait while you get the calculator
5. If you have already had your birthday this year add 1755 .... If you haven't, add 1756.
6. Now subtract the four digit year that you were born.
You should have a three digit number
The first digit of this was your original number
The next two your age.. ( hopefully :whistling: )
