Welcome to the Quilting Board!

OR

1. pi

My calculator gives the value of pi as: 3.14159365359

My calculator give the value of 22/7 (3-1/7) as: 3.14285714286

22/7 has a repeating decimal as the value and, as far as I know, pi goes on forever.

Anyway -

for most purposes in my life - as in drafting a pattern - 22/7 - works well enough for most calculations.
0.00126 - a bit more than one-thousandth of an inch variation will probably work well enough with 'a scant quarter inch' seam

You're so funny!

3. The calculator value is much more accurate. 22/7 is an approximation for use with fractions. As you say, however, either one is close enough to get you scant quarter seamline.

4. Pi...i like mine cherry!!! (Lol)

5. Huh?? LOL that is very odd.

6. ooh, good one, hahaha

7. My Granddaughter is taking college math and not getting it. I'm no good, I think the basics are plenty for the average person. I learned fractions by using them in cooking and baking, doubling recipes made them second nature to me. I do love calculators.

Spelling use to be the easiest thing for me but as I age, not so much.

8. Help with college algebra

I teach math and will suggest that your granddaughter first see if there is a tutoring center at her college that can help. These are often staffed by math geeks who work there as part of their work-study financial aid. If not, there is a book called Algebra to Go (available on Amazon) that will help. It is part of a series that includes Math on Call and a couple more. These are not workbooks but are math reference books. I always find that they explain things clearly and simply, and use easy-to-understand drawings to help. Pi can be pretty straightforward if you have a good calculator and approximate it as 3.14, but some professors want it approximated as something longer then you end up rounding all of your answers and then the trouble begins......

9. I still think that 22/7 is a good APPROXIMATION of the ratio of a circle's circumference to it's diameter.

It seems very logical to me from a metaphysical/numerological viewpoint.

10. I want to see the movie that just came out.

11. Who cares about one-thousandth of an inch!! Quilting is supposed to be fun, not requiring a math geek. If all the seams are the same, the quilt will look fine.

12. Pi I would like apple please alamode!

13. As that was flying over my head, I never even had a chance to look up.

14. I'm making 3 for Thursday. Apple, pumpkin and banana cream pie.

15. Wo. Someone needs to call ER for bearisgray! LOL

16. Just trying to say that 22/7 (3-1/7) is a close enough approximation to whatever the 'actual' value of pi is for most of my purposes.

I totally agree with you.

18. Math was not my strong suite. I know how to use the 60 degrees on my quilting ruler to get a diamond, but don't ask me to explain it mathimatically.
