โœจ The Magic Shortcut Formula
✨ Magic Formula for (N5)²: First part: N * (N + 1) Last part: 25 Combine them: [N * (N+1)] 25. Example: 65² -> 6 x (6+1) | 25 = 6 x 7 | 25 = 4225! Example: 95² -> 9 x 10 | 25 = 9025!
✨ जादुई सूत्र: (N5)² = [N * (N+1)] | 25 उदाहरण: 65² = 6 x 7 | 25 = 4225! उदाहरण: 95² = 9 x 10 | 25 = 9025! उदाहरण: 115² = 11 x 12 | 25 = 13225!

๐Ÿ”ข Step-by-Step Mental Calculation:

1
Step 1: Take the digits before the last '5' (call it N).
2
Step 2: Multiply N by its immediate successor (N + 1).
3
Step 3: Append '25' at the end.
1
चरण 1: इकाई के 5 को छोड़कर बाकी बची संख्या (N) लें।
2
चरण 2: N को उसके अगले अंक (N+1) से गुणा करें।
3
चरण 3: प्राप्त संख्या के अंत में '25' चिपका दें।
๐Ÿ’ก Practice Demonstration:
Problem: Calculate 85² in mind without using pen.
เคชเฅเคฐเคถเฅเคจ: बिना पेन छुए 85² का मान ज्ञात करें।
โšก Lightning Solution:
N = 8. Multiply 8 x (8+1) = 8 x 9 = 72. Append 25 -> 7225. Done!
N = 8. 8 x 9 = 72. अंत में 25 लगाएं -> 7225!

Exam Trap Alert & Common Calculation Pitfalls

⚠️ Exam Trap: The trick strictly requires the unit digit to be 5. For other endings, use the general algebraic (a+b)² = a² + 2ab + b² base method!

⚠️ परीक्षा ट्रैप: यह ट्रिक केवल उन संख्याओं के लिए है जिनका इकाई अंक 5 हो।
