📘 Detailed Instructions

Binary ↔ Decimal: Convert between base 2 and ordinary decimal numbers. Example: 1010₂ = 10₁₀.

Hex ↔ Decimal: Convert between base 16 and decimal. Hexadecimal uses 0–9 and A–F, where A=10 through F=15.

Binary ↔ Hexadecimal: Convert directly between the two bases. One hexadecimal digit corresponds to four binary bits.

For binary answers, spaces, underscores, and an optional 0b prefix are accepted.
For hexadecimal answers, uppercase/lowercase letters and an optional 0x prefix are accepted.
For decimal answers, commas are accepted. Leading zeros do not affect scoring.
