Game Objective

You'll be shown an 8-bit binary number (8 digits of 0s and 1s). Your goal is to convert it to its decimal (base-10) equivalent.

Game rules:

  • Each game has 10 rounds
  • You get 3 attempts per question
  • Score points for correct answers

Understanding Binary

Binary is a base-2 number system, using only 0s and 1s. Each position represents a power of 2.

8-bit binary position values:

Position76543210
Value (2n)1286432168421

How to Convert

Follow these steps to convert binary to decimal:

  1. 1Write down the binary number (e.g., 10000010)
  2. 2Label each position from right to left, starting at 0
  3. 3Multiply each digit by 2 raised to its position power
  4. 4Add all the results together

Example

Convert 10000010 to decimal:

Binary:

1 0 0 0 0 0 1 0

Power (right to left):

7 6 5 4 3 2 1 0

Value (2n):

128 64 32 16 8 4 2 1

Calculation:

  • 1 × 128 = 128
  • 0 × 64 = 0
  • 0 × 32 = 0
  • 0 × 16 = 0
  • 0 × 8 = 0
  • 0 × 4 = 0
  • 1 × 2 = 2
  • 0 × 1 = 0

128 + 0 + 0 + 0 + 0 + 0 + 2 + 0 = 130

Answer: 130

Tips for Success

  • Start from the right (least significant bit)
  • Remember: 20 = 1, 21 = 2, 22 = 4, 23 = 8, etc.
  • Only 1s contribute to the sum (0s = 0)
