Can you solve the IB Encryption Conundrum? This simple high school math proof reveals a secret constant hidden within any three consecutive integers, and we'll show you how to find it using deductive reasoning.

In this essential high school Math tutorial, we dive into a fascinating real-world problem inspired by cryptography. Imagine needing to prove a mathematical claim so rigorously that it can be used as the foundation for a secure encryption algorithm. That's our mission today! We'll guide you step-by-step through a complete deductive proof, demonstrating how to prove that the square of the middle of three consecutive integers, minus the product of the other two, always results in the constant value of 1.

This lesson is perfect for high school and IBDP Math students (both AI and AA SL/HL) looking to master proof-based questions. We'll break down the core concepts you absolutely need to know for your exams. First, we define what a simple deductive proof is and how to structure one logically from general premises to a concrete conclusion. Then, we tackle a common point of confusion: the critical difference between an equality (=), which is true for specific values, and an identity (≡), which is true for ALL values. Understanding and using these symbols correctly is a key skill that examiners look for.

Join us on this problem-solving journey as we transform a complex-sounding claim into a simple, elegant algebraic proof. By the end of this video, you'll not only have the answer to the encryption conundrum but also a stronger foundation in logical reasoning and algebraic manipulation that will boost your confidence in higher-level mathematics.
