Can you solve 101² − 99² in just a few seconds - without a calculator? 🧠
Most people start squaring both numbers… but there’s a faster, smarter trick hidden inside this expression!
In this short and fun math video, we’ll use the difference of two squares formula to solve it instantly: a² - b² = (a - b)(a + b)
With this simple idea, you’ll see how to go from “complicated-looking” to “done in seconds!”
What You’ll Learn:
A powerful mental math shortcut
How to use the difference of squares formula
How to simplify big number problems quickly
How this trick works for any similar question (like 1001² − 999², 51² − 49², etc.)
