BINARY TO DECIMAL CONVERSION:�
To convert a binary number to decimal, follow these steps:
1. Write down the binary number.
2. Start from the rightmost digit and assign each digit a power of 2, starting from 2^0, 2^1, 2^2, and so on.
3. Multiply each digit of the binary number by its corresponding power of 2.
4. Sum up the results of the multiplication from step 3 to get the decimal equivalent of the binary number.
Example:
Let's convert the binary number 101010 to decimal.
1. Write down the binary number: 101010.
2. Start from the rightmost digit and assign powers of 2: 2^0, 2^1, 2^2, 2^3, 2^4, 2^5.
3. Multiply each digit of the binary number by its corresponding power of 2:
(1 * 2^0) + (0 * 2^1) + (1 * 2^2) + (0 * 2^3) + (1 * 2^4) + (0 * 2^5).
4. Sum up the results: 1 + 0 + 4 + 0 + 16 + 0 = 21.
Therefore, the binary number 101010 is equal to the decimal number 21.
