Suppose the two propositions being joined are P and Q. Each of these propositions will have two possible truth values: true, or false.

What are the two types of fallacy?

How to find it, where does it go wrong? 2 = 1 2 = 1, and state why and where the proof is wrong. In the above proof, you’ll be amused how can this happen.

How do you prove a fallacy step by step?

The Fallacious Proof: Step 1: Let a=b. Step 2: Then , Step 3: , Step 4: , Step 5: , Step 6: and . Step 7: This can be written as , Step 8: and cancelling the from both sides gives 1=2. See if you can figure out in which step the fallacy lies.
