Fwd: Math working group invite

Greg has given us some discussion material for the discussion on Thursday:

Here is the link to the Google sheet from the CCWG:
> https://docs.google.com/spreadsheets/d/1h-8k_bwQ1bO7gusb0O2DfcEs0DZUAo6QVGYZuVjWVB8/edit#gid=0
> I am also attaching it as an Excel file. In addition I am attaching a draft
> of narrative text that is related. I was not part of the group when the
> spreadsheet was developed, and in looking at it, I have some questions
> about what seem to be the recommendations for speaking some of the content.
> Nonetheless, here are the files.
