Basic Proofs

Mathematics - Logic and Reasoning

A proof is like building a path step by step to show why something is true.

抂芁

Think of a proof as being a detective who needs to solve a puzzle 🔍. Just like detectives use clues and evidence to reach a conclusion, mathematicians use proofs to show why mathematical statements are true. We start with facts we know are true and use logical steps to reach our final answer.

詳现説明

Starting Point 📌

Every proof begins with something we know is true (like given facts or definitions). It's like starting a journey with a map and knowing your starting location.

Logical Steps ➡

Each step in a proof must follow logically from previous steps. It's like building a bridge - each piece must connect firmly to the previous one.

Clear Reasoning 💭

We must explain why each step is true, just like explaining to a friend why you chose a particular route to get somewhere.

Conclusion 🎯

The proof ends when we reach our target statement. Like completing a puzzle, all pieces must fit together to show the final picture.

䟋題

  • Proving why all squares have four equal sides is like showing someone how to make a perfect sandwich - you start with the definition of a square, then explain step by step why each side must be equal.
  • If you want to prove why 2 + 2 = 4, it's like explaining to a child why two pairs of shoes make four shoes - you can physically show them and count.
  • Proving that all right angles are 90 degrees is like showing why a door needs to open at exactly that angle to stand straight - you can demonstrate it with real objects and measurements.
