have you found any mistakes?
let me see
is it because he wrote 4.4 as positive?
so whats the complete answer?
this is an open ended question. You identified the mistake, just say why it was wrong.
why was it wrong though
because you can't just change the sign of an expression
is it wrong because he wrote the additive inverse property wrong
yeah you can say that.
what would you say
I don't think your teacher's interested in what I would say. There are many, many, many correct answers to this question. Your answer is correct. You should use it, because I'm sure before the end of the week someone else will ask this question, and it'll look like cheating if you all turn in what I would say.
no dont worry im going to write what i said, but i just want to know your opinion : @peachpi
I'd use what I said above. You can't just change a sign for no reason
ok thanks for your help :)
i have some other questions but ill tag you :)
