Things your kids will never know - old school tech!

Deozaan:
I do remember that if you didn't have a Pi key (I didn't!), you could always generate it by dividing 355 by 113.

It was easy to remember because it was just the first three odd numbers duplicated:

113355

Split it in the middle

113     355

and divide the bigger number by the smaller and you get

I always thought it was 22/7. Though 355/113 is certainly a lot more accurate for estimating pi.

I guess I was part of the younger generation the teachers all thought was too stupid to remember clever mnemonics like that.

Ha! You're right, Deozaan - I learned it as 22/7 as well. I'd forgotten about that  :o

Deozaan:
must be an age thing, if [cursive] isn't normal writing, what is??  :huh:

When I learned how to write in kindergarten, "normal writing" was called "denelian" AKA print. I don't think I learned cursive until maybe 2nd or 3rd grade. I only used cursive when required to by teachers, and to this day, I only use cursive for my signature.

An example practice sheet similar to those I used in kindergarten for learning denelian:

Not a formula for Shell oil, but one that if followed may yield a cheaper and altogether more cozy way of heating your home:

62 O2 (g) + C52H84O22 (s) --> 52 CO2 (g) + 42 H2O (g)

I seem to be needing lot's of help these days -
anyone else understanding that ?
I tried reading out loud but dont know what C52H84O22 is
Actually searching for it I found
http://answers.yahoo.com/question/index?qid=20061130123830AAh3Sxc which gives the answer ...

Although to be honest it was always easier for me to remember the first few digits of pi rather than some obscure division problem.

Just from memory I can go to 5 decimal places before I start to get confused, and that's nearly as accurate as 355/113 and definitely as accurate as you'd ever need for a calculator that doesn't have pi built in to it.
