🧮 PART 1: SQUARE TRICKS (within seconds!)


✅ 1. Square of numbers ending with 5

💡 Use Sutra: Ekadhikena Purvena (One more than the previous)

➡️ Formula: If a number = x5, then (x5)² = x × (x+1) and add 25

🧠 Examples:

  • 25² = 2×3 = 6 → Add 25 → 625
  • 75² = 7×8 = 56 → Add 25 → 5625
  • 95² = 9×10 = 90 → Add 25 → 9025

🟢 Superfast trick for banking/SSC!


✅ 2. Square of numbers near base (100, 1000)

💡 Use Sutra: Nikhilam Navatashcaramam Dashatah (All from 9 and the last from 10)

➡️ For numbers near 100:

Step:

  • Find difference from 100 (positive or negative)
  • Subtract crosswise
  • Multiply difference part

🧠 Example:
97² →
97 is 3 less than 100 → (97 – 3 = 94)
3² = 09
✔️ Answer: 9409

102² →
102 is 2 more → 102 + 2 = 104 → 2² = 04
✔️ Answer: 10404


✅ 3. Square of any 2-digit number (General Trick)

💡 Use: (a + b)² = a² + 2ab + b²

➡️ Split number into tens and unit digits
🧠 Example: 47²
a = 40, b = 7
= 40² + 2×40×7 + 7²
= 1600 + 560 + 49 = 2209


✅ 4. Special Trick: Square of numbers between 50 to 60

Formula:
(50 + x)² = 2500 + 100x + x²

🧠 Example: 53²
= 2500 + 100×3 + 9 = 2809


✅ 5. Square of any number ending in 1, 9, 2, 8

Use formula:
(x + y)² = x² + 2xy + y²

🧠 Example: 39² = (40 – 1)² = 40² – 80 + 1 = 1521


🧮 PART 2: CUBE TRICKS (Fast and Easy)


✅ 1. Cube of numbers ending in 1 to 9 (memorize)

📌 1³ = 1
📌 2³ = 8
📌 3³ = 27
📌 4³ = 64
📌 5³ = 125
📌 6³ = 216
📌 7³ = 343
📌 8³ = 512
📌 9³ = 729
📌 10³ = 1000

🔁 Know these well — very useful in reasoning and simplification.

✅ 2. Cube of 2-digit numbers (Algebra trick)

💡 Formula: (a + b)³ = a³ + 3a²b + 3ab² + b³

🧠 Example: 12³
Split: 10 + 2
= 1000 + 3×100×2 + 3×10×4 + 8
= 1728


✅ 3. Cube of numbers near 100

Use (x ± y)³ = x³ ± 3x²y + 3xy² ± y³

🧠 Example: 101³
= (100 + 1)³ =
1000000 + 3×10000×1 + 3×100×1 + 1

= 1030301


✅ 4. Last digit trick for cubes in options

✅ Cube of number ending with:

Unit DigitLast Digit of Cube
11
28
37
44
55
66
73
82
99
00

Helps in eliminating wrong options in MCQs.


✅ 5. Trick for cube of numbers like 11, 21, 31, 41…

11³ = 1331
21³ = 9261
31³ = 29791

➡️ Use (x + 1)³ formula or remember 1st few values.


🧠 Final Tips to Master Vedic Square & Cube Tricks:

✔️ Practice daily for speed
✔️ Don’t memorize blindly — understand the patterns
✔️ Use base method for close-to-100 numbers
✔️ For mental math, always break numbers logically
✔️ Compete with a timer (simulate exam feel)
