         *Note: On 6.22 if the GradeGrinder says your proof is correct, I don't care if it mirrors the informal proof.
         **Note: On 6.24-6.27 while writing out an informal proof will help you, you do not have to turn any in on paper.
         6.32 contains a typographical error. The third premise contains an extra close parenthesis at the end. Scratch it out.
