🌟 Amazing job! You're a Binary Master!
To convert a binary number to a decimal number, multiply each binary digit by 2 raised to its position power (starting from right at 0), then add the results together.
For the binary number 11111111:
1×2⁷ + 1×2⁶ + 1×2⁵ + 1×2⁴ + 1×2³ + 1×2² + 1×2¹ + 1×2⁰
= 128 + 64 + 32 + 16 + 8 + 4 + 2 + 1
= 255
Answer: 255 (decimal)
