"ever try casting out 9's?"

Cast out that apostrophe first.

I normally don't use "'"s in pluralizing non-words (numbers, TLAs, and such), but it now seems so commonplace that in this instance I chose to use it so EVERYONE would be able to understand what I was trying to convey.

Besides this is sort of a MATH thread rather than English usage. Mathematicians/Scientists commonly use their own notation so as to confuse as many as possible and I didn't attend Harvard or Cambridge.

So, EXCUUUSSSSSEEEEEE MMEEEEE!!!!

Thank ya vera much.

***Cast out that apostrophe first.***

You're mistaken. I did not write the sentence you referred to. Pardon me, "to which you referred."

LOL
No apostrophes in plurals or possessive pronouns!!!
When I replied to Paladin2's post, however, 9s and 6s didn't look well on screen. I resorted to sixes.
