📌 What is HEX (Hexadecimal Number System)?

The Hexadecimal system (Base-16) is a number system that uses 16 symbols:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F

👉 Here:

• 0–9 represent decimal 0 to 9
• A = 10, B = 11, C = 12, D = 13, E = 14, F = 15

👉 Example: HEX 1A means:
= (1 × 16¹) + (10 × 16⁰)
= 16 + 10
= Decimal 26

🛠️ Manual Conversion: HEX to Decimal

To convert HEX to Decimal manually, follow this formula: Decimal=(dn×16n)+(dn−1×16n−1)+…+(d0×160)Decimal = (dₙ × 16ⁿ) + (dₙ₋₁ × 16ⁿ⁻¹) + … + (d₀ × 16⁰)Decimal=(dn​×16n)+(dn−1​×16n−1)+…+(d0​×160)

👉 Example 1: Convert HEX 2F to Decimal

• 2 × 16¹ = 32
• F = 15 × 16⁰ = 15
  = 32 + 15 = 47

👉 Example 2: Convert HEX 1A3 to Decimal

• 1 × 16² = 256
• A = 10 × 16¹ = 160
• 3 × 16⁰ = 3
  = 256 + 160 + 3 = 419
