Answer for screen readers
The decimal equivalent of the binary number $1010$ is $10$.
Steps to Solve
- Identify the positions of the binary digits
In binary, each position represents a power of 2, starting from the rightmost digit. For the binary number 1010, the positions are as follows:
- $2^3$ (8)
- $2^2$ (4)
- $2^1$ (2)
- $2^0$ (1)
- Determine the value of each digit
Now we multiply each binary digit by its corresponding power of 2:
- The first digit (from the right) is 0: $0 \times 2^0 = 0 \times 1 = 0$
- The second digit is 1: $1 \times 2^1 = 1 \times 2 = 2$
- The third digit is 0: $0 \times 2^2 = 0 \times 4 = 0$
- The fourth digit is 1: $1 \times 2^3 = 1 \times 8 = 8$
- Sum the values
Now, we add up all the values we calculated:
$$ 0 + 2 + 0 + 8 = 10 $$
- Write the final decimal equivalent
The decimal equivalent of the binary number 1010 is therefore 10.
The decimal equivalent of the binary number $1010$ is $10$.
More Information
When converting from binary to decimal, each binary digit represents a power of 2. The binary numbering system is base-2, while the decimal system is base-10.
Tips
- Forgetting to multiply by the correct power of 2: Make sure to keep track of the powers starting from $0$ on the right.
- Incorrectly adding the values: Double-check your addition to ensure accuracy.
