If a rectangle R is subdivided into a nite number R1; : : : ; Rn of nonoverlapping subrectangles (nonoverlapping means two of the subrectangles can have only boundary points in common), then. n. A(R) = X A(Rk) :

   Math 150s Proof and Mathematical Reasoning Jenny Wilson A Primer on Mathematical Proof A proof is an argument to convince your audience that a mathematical statement is true. It can be a calcu-lation, a verbal argument, or a combination of both. In comparison to computational math problems, proof

   1 Theorems and conjectures. As mathematicians and students of mathematics, it is our job to separate those mathematical propositions that are true from those that are false. The method that mathematicians use to verify that a proposition is true is called deductive proof.

   What is mathematical proof?

   • Mathematical proof is absolute, which means that once a theorem is proved, it is proved for ever. Until proven though, the statement is never accepted as a true one. Writing proofs is the essence of mathematics studies. You will notice very quickly that from day one at university, lecturers will be very thorough with their explanations.

   What is the difference between a Venn diagram and a mathematical proof?

   • From Venn diagrams to rigorous math. What is a Proof? proof is an argument that demonstrates why a conclusion is true, subject to certain standards of truth. mathematical proof is an argument that demonstrates why a mathematical statement is true, following the rules of mathematics.

   How do mathematicians prove a proposition is true?

   • The method that mathematicians use to verify that a proposition is true is called deductive proof. Roughly speaking, a deductive proof is a step by step argument that uses known facts and applies valid rules of deduction to build to a desired conclusion. A mathematical proposition that has been proved to be true is called a Theorem.

   What is the search for a mathematical proof?

   • \The search for a mathematical proof is the search for a knowledge which is more absolute than the knowledge accu-mulated by any other discipline." A proof is a sequence of logical statements, one implying another, which gives an explanation of why a given statement is true.

   What are the different types of mathematical proof?

   • There are dierent styles of mathematical proof, from strictly formal proofs to informal. In strictly formal proofs, the rules are very clear and precise. Formal proofs are written symbolically rather than in English.

   Why is writing proofs important in mathematics?

   • Writing proofs is the essence of mathematics studies. You will notice very quickly that from day one at university, lecturers will be very thorough with their explanations. Every word will be de ned, notations clearly presented and each theorem proved. We learn how to construct logical arguments and what a good proof looks like.

   For every integer x, if x is odd, then x2 is. . . This dialogue illustrates several important points. First, a proof is an explanation which convinces other mathematicians that a statement is true. A good proof also helps them understand why it is true.
