What are the missing order of operations for 8—— 2 —— 6 —— 5—— 1=11

You're using "he", then "she" for your partner:
are you serious....or is your coffee heavily laced?????

I noticed that too but did not want to comment on it. I don't think that the OP's coffee is heavily laced.

“He or she” My private life is private, nothing to do with maths, I discuss this with family and close friends.thank you for for those who answered. my watts query.

For what it's worth, I assumed "partner" meant a partner in a school project ...

Perhaps your "partner" turned the 6 upside down:
(8 - 2 + 9)/5) * 1 = 3
