You must first determine exactly what it is you are. Proposition after proposition proof after proof. End with notation like QED qed or.
They are considered basic because students should be able to understand what the proof is trying to convey and be able to follow the simple algebraic manipulations or steps involved in the proof itself.
You will learn a lot about constructing proofs from studying geometry particularly with regards to projective geometry in the plane and geometry of the sphere. Let Pn represent 2n 1 is odd. In highschool or at GCSE students are often taught about triangular geometry and an introductory university module in Geometry will formalise these concepts ultimately with the idea of gaining practice understanding and writing geometric proofs. Some proofs use other strategies.
