thanks Joe:

I just did some test:

1- This only seems to happen with notes on the iphone, not notes on laptop. Odd no?

2- I do not see this behavior elsewhere.. or at least I just tested in Word and Text Edit on leptop. It does not happen.

3- Siri.. I agree crazy. I don't know what promted the bit about dication, but I totally agree. I use it all the time, dication (Siri controls that?), I never use Siri, but I use dication, and wow, if you don't proofread, (and sometime I forget), very nasty things can go out...

In stystem pref, I don't know if I want to uncheck add period after double space. I think that's good for letter writing. This is something different. I'm typing a street address down on the fly — 23456 Jones St. and then Notes is making these addresses an arithmetic situation and then adding another number when I hit return! I just writing text and now I'm into math, without my permission.
