# 11 Proven Proof Techniques Non-Math Majors Should Know

Proofs is the heart of mathematics.  It is what differentiates mathematics from other sciences.  In mathematical proofs, we can show that a statement is true for all possible cases without showing all the cases. We can be certain that the sum of two even numbers is  even without adding all the possible pairs.

For those who are “non-math people,” the proof techniques below will help you, but the “math people” are probably those who are going to enjoy them more.

1.) Proof by Obviousness

Example: “The proof is so clear that it need not to be mentioned.”

2.) Proof by Intimidation

Example 1: “Don’t be stupid. It’s true.”

Example 2: “It’s trivial”

3.) Proof by Deception

Example: “Now everyone turn their backs…”

4.) Proof by Lack of Sufficient Time

Example: ”Because of the time constraint, I’ll leave the proof to you.”

5.) Proof by Plagiarism

Example: “As we see on page 85, it is true.”

6.)  Proof by Intuition

Example: “I have this gut feeling that it’s true.”

7.) Proof by Calculus

Example: “The proof requires calculus, so it must be true.”

8.) Proof by Convenience

Example: “Well, it would be nice if it were true.”

9.) Proof by Authority

Example: “Isaac Newton said it, so it must be true.”

10.) Proof by Profanity

Example is not appropriate for this blog.

11.) Proof by Terror

This proof is very effective if “Proof by Intimidation” fails.
