1. Write down the binary number, starting from the rightmost digit and moving to the left. Assign each digit a power of 2, starting with 2^0 for the rightmost digit, 2^1 for the next digit to the left, 2^2 for the next, and so on.
2. Multiply each digit of the binary number by its corresponding power of 2.
3. Add up all the results from step 2 to get the decimal equivalent.
For example, let's convert the binary number 1011 to decimal:
1. Start from the rightmost digit: 1 0 1 1.
2. Assign powers of 2 to each digit: 2^0 2^1 2^2 2^3.
3. Multiply each digit by its corresponding power of 2:
- 1 * 2^0 = 1
- 1 * 2^1 = 2
- 0 * 2^2 = 0
- 1 * 2^3 = 8
4. Add up the results: 1 + 2 + 0 + 8 = 11.
So, the binary number 1011 is equivalent to the decimal number 11.
