3*-2-1-3(-2)
And I got -13. Is that correct??
Answered by Summer Moriarty
I am going to assume that this is correct just cause that's the answer that I got and no on is willing to check my answer so I am going for it. Bobpursley, you said that you would check my answer when I thought that I had the correct answer and now here I am assuming that its right because you wont check it for me.
Answered by Ms. Sue
No, it is not - 13.

Well thanks for telling me now that I have already sent it in and got the question wrong when I could have had the question right. Next time speed things up on answering the students when they go and post a question with their answers.

Speed it up??

You are told on the Post a New Question page to have patience, that tutors here are VOLUNTEERS -- who don't have to show up at all!

A time-out for a couple of days might help you think this through, and read EVERYTHING on this webpage:
