# Thread: Speaking of former math teachers...

1. ## Speaking of former math teachers...

Not a puzzle, but a previous comment reminded me of a college prof that insisted we learn PI to more decimal places than most would ever want/need.

The phrase to trigger your memory was: May I have a large container of coffee? (count the letters).
If you got the coffee and were polite and said "thank you," you got 2 more decimal places.

Never forgot it: 3.141592653(5898...remembered those too for some odd reason).

2. 3.14159 26535 89793 23846 26433 83279 50288 41971 69399 37510 58209 74944 59230 78164 06286 20899 86280 34825 34211 70679............

your last digit seems wrong assuming the ( was a typo and not a digit=9
in which case the second 3 was the last correct digit as posted

my son had a poster with a couple thousand digits
interesting but useless

3. No, type a typo...I was just adding a few more digits, and rounded the last one. 3.1415926535898 (actually, 897...)

I wonder who/what might ever use it to some extremely large number of decimal places? Space calculations? Or just mathematical challenges to find more digits.

4. I remember PI to 3.141592654 but also remember using 22/7 for rough calculations!
