This is clever

1. Pick a number between 1 & 9
2. Multiply it by 2
3. add 5
4. Multiply by 50
5. now add 1753 or if you have already had your birthday this year add 1754
6. now subtract the year you were born (eg 1954)
7. you shoud have 3 numbers the first was the number picked & the last 2 are how old you are??
