📏 Understanding Binary and Decimal Numbers

Binary System (Base-2):
The binary system is a numerical system that uses only two digits — 0 and 1. It is the foundation of digital computing, electronics, and programming. Each digit in a binary number represents a power of 2.
Example: Binary 1011 = (1×2³) + (0×2²) + (1×2¹) + (1×2⁰)

Decimal System (Base-10):
The decimal system is the most common numerical system used in daily life. It uses ten digits (0 to 9) and powers of 10. It is widely applied in mathematics, finance, trade, and everyday calculations.

👉 Conversion Value:
Each binary digit (bit) can be expanded into powers of 2 and then summed up to get the decimal value.

⚖️ Formula to Convert Binary to Decimal

The conversion formula is simple:

Decimal = (bₙ × 2ⁿ) + (bₙ₋₁ × 2ⁿ⁻¹) + … + (b₁ × 2¹) + (b₀ × 2⁰)

Where b represents each binary digit (0 or 1), and n is the position of the digit, starting from 0 on the right-hand side.

📚 Examples of Conversion

Convert Binary 1010 to Decimal

(1×2³) + (0×2²) + (1×2¹) + (0×2⁰) = 8 + 0 + 2 + 0

✅ So, Binary 1010 = Decimal 10

Convert Binary 11101 to Decimal

(1×2⁴) + (1×2³) + (1×2²) + (0×2¹) + (1×2⁰) = 16 + 8 + 4 + 0 + 1

✅ So, Binary 11101 = Decimal 29

Convert Binary 100011 to Decimal

(1×2⁵) + (0×2⁴) + (0×2³) + (0×2²) + (1×2¹) + (1×2⁰) = 32 + 0 + 0 + 0 + 2 + 1

✅ So, Binary 100011 = Decimal 35

Convert Binary 1101101 to Decimal

(1×2⁶) + (1×2⁵) + (0×2⁴) + (1×2³) + (1×2²) + (0×2¹) + (1×2⁰) = 64 + 32 + 0 + 8 + 4 + 0 + 1

✅ So, Binary 1101101 = Decimal 109

These examples show how binary numbers of varying lengths can be quickly converted into decimals for use in programming, mathematics, and technology.
