🔷 Sutra Used: Urdhva Tiryagbhyam
🧠 Means “Vertically and Crosswise”
➡ A brilliant method from Vedic Math to simplify large multiplications using pattern-based criss-cross calculation — faster than traditional methods.
🔢 Multiply 3-digit × 3-digit: Step-by-Step with Example
✨ Example: 321 × 213
Break the numbers:
321 → A B C → 3 2 1
213 → P Q R → 2 1 3
Now apply criss-cross multiplication and carry:
| Step | Operation | Result |
| 1 | Units: 1 × 3 | 3 |
| 2 | Cross: (2×3) + (1×1) | 6 + 1 = 7 |
| 3 | Triple Cross: (3×3) + (2×1) + (1×2) | 9 + 2 + 2 = 13 |
| 4 | Cross: (3×1) + (2×2) | 3 + 4 = 7 |
| 5 | Left: 3 × 2 | 6 |
✅ Combine the digits with carry:
321 × 213 = 68373
🔢 Multiply 4-digit × 4-digit: Master Trick
✨ Example: 1234 × 1234
Let’s simplify this step-wise using the same vertical and diagonal approach.
Split both numbers:
1234 → A B C D
→ 1 2 3 4
Now apply vertical and cross patterns:
| Step | Operation | Result |
| 1 | Last digits: 4 × 4 | 16 |
| 2 | (3×4) + (4×3) | 12 + 12 = 24 |
| 3 | (2×4) + (3×3) + (4×2) | 8 + 9 + 8 = 25 |
| 4 | (1×4) + (2×3) + (3×2) + (4×1) | 4 + 6 + 6 + 4 = 20 |
| 5 | (1×3) + (2×2) + (3×1) | 3 + 4 + 3 = 10 |
| 6 | (1×2) + (2×1) | 2 + 2 = 4 |
| 7 | 1 × 1 | 1 |
Carry over and combine:
✅ 1234 × 1234 = 1522756
🔹 Special Shortcut: Numbers Close to 1000 or 1001
✨ Example: 1001 × 1023
- Base: 1000
- 1001 = 1000 + 1
- 1023 = 1000 + 23
📌 Apply this Vedic-style trick:
(1000 + 1)(1000 + 23)
= 1000² + (1 + 23)×1000 + (1×23)
= 1,000,000 + 24,000 + 23 = ✅ 1,024,023
🧠 Why This Works?
The Urdhva Tiryagbhyam method reduces repeated steps and allows you to compute large multiplications in just 5–7 lines. With a little practice, it becomes lightning-fast!
