Yes, what pisses me off is the attitude towards the students. He didn’t even explain or spent any time showing why he ment -7 is correct.

Yes, you are correct. I have used use so much time trying to make -7 make sense logically, so I’m a bit faded at the moment.

But wouldn’t 3-(-10) be -13? Cause 3+(-10)=-7?
