additve identity if you search up is about something like zero

Do you have notes of each of the different options so you know what each one is about?

anonymous · Answer

im not really sure

atildathehun · Answer

ok, as we go over each one i recomend looking them up for their definitions. I am sorry but I am not very good at explaining what each of these proofs are. Though I do know what they are. lol life is funny that way.

atildathehun · Answer

so it is not the first one, does the second one make sense?

atildathehun · Answer

I have never heard of a proof called by construction before so I am going to rule that one out.
