---

🧮 Arithmetic Shortcuts

Addition/Subtraction:

• Use “round and compensate” for fast mental addition.
  Example: 498 + 247 → (500 + 247) – 2 = 745

Multiplication:

• Vedic Maths: Cross multiplication method for numbers near base (100, 1000).

• Example: 104 × 106 → Use (Base = 100): 100 + 4 × 100 + 6 = 110 + (4×6) = 110 + 24 = 11024

Division:

• Use reciprocal tricks for dividing by common numbers like 5, 25, 125.

---

📐 Algebra Shortcuts

• Identity Simplification:
  a² – b² = (a – b)(a + b) saves tons of time

• Solving Linear Equations:
  Cross-multiply trick for two-variable linear equations.

• Quadratics:
  Shortcut formula method: Use constant/product and sum/middle term logic.

---

📏 Geometry Shortcuts

• Area of triangle using Hero’s formula (only when sides are given)

• Memorize shortcuts for Pythagorean triplets

• For angles: Use “sum of angles in polygon = (n-2)×180°” instead of lengthy calculations.

---

📐 Trigonometry Shortcuts

• Create your own mnemonic to remember sin/cos/tan tables.

• Learn co-function identities: sin(90° – θ) = cos(θ)

• Solve expressions like sin²θ + cos²θ = 1 in less than 5 seconds!

---

📊 Mensuration Shortcuts

• Cylinder Surface Area: 2πr(h + r)
  Remember the formula like a chant!

• Cube Diagonal Trick: √3a

• Cone Volume: Just remember 1/3 × base × height

---

📈 Statistics and Probability Shortcuts

• Mean shortcut: Use (Σx)/n, but estimate first to avoid heavy calculations

• Probability: Focus on favorable cases over total cases—use logic instead of formulas when possible.

---

🔢 Number System Tricks

• Divisibility Rules:

  • 3: Sum of digits divisible by 3

  • 11: Alternating sum of digits divisible by 11

• Last Digit Trick:

  • Powers of numbers (like 7⁴) – Use cycles!

• HCF/LCM:

  • Use product method: (HCF × LCM = Product of numbers)
