comment Diagonal Matrices with Zero on Diagonal
Thank you. Yeah, I just wanted to make sure that these are diagonal as well as I need to prove that they are zero divisors.

comment Proof by Induction: Alternating Sum of Fibonacci Numbers
My question was a little more specific, don't you think? I knew it was induction, I just didn't know where I went wrong in my proof.

comment Proof by Induction: Alternating Sum of Fibonacci Numbers
Thank you. I was originally just adding 1 to the subscript instead of to the $n$. I also didn't realize that I needed to repeat both the $-f_{2k-1}$ and the $f_{2k}$ with the $+1$ to $k$. Your answer helped me find where I was going wrong!
