Your "friend" has shown you a “proof" he wrote to show that 1 = 3. Here is the proof: Proof. I claim that 1 = 3. Of course we can do anything to one side of an equation as long as we also do it to the other side. So subtract 2 from both sides. This gives -1 = 1. Now square both sides, to get 1 = 1. And we all agree this is true. QED What is going on here? Is your friend's argument valid? Is the argument a proof of the claim 1 = 3? Carefully explain using what we know about logic.
