Fast Modular Exponentiation with Binary Method ⚡

Learn how to compute exponential modular expressions efficiently using the binary (fast exponentiation) method. This technique is essential in number theory, computer science, cryptography, and competitive mathematics—and in this video, we break it down in a clear, intuitive way.

You’ll learn:

Why modular exponentiation is important

How to convert exponents into binary

How to apply repeated squaring

How to reduce calculations using modular arithmetic

Fully worked examples from start to finish

If anything wasn’t explained clearly, let me know—I’m always happy to revisit concepts or create a follow‑up video with more examples.
