Answer for screen readers
The decimal representation of the hexadecimal number $100$ is $256$.
Steps to Solve

Identify the hexadecimal value The given hexadecimal number is $100$.

Break down the hexadecimal digits In the hexadecimal system, each digit represents a power of 16. The hexadecimal number $100$ can be broken down into:
 $1 \times 16^2$
 $0 \times 16^1$
 $0 \times 16^0$
 Calculate each term Now, we calculate the value of each term:
 For the first term, $1 \times 16^2 = 1 \times 256 = 256$.
 For the second term, $0 \times 16^1 = 0 \times 16 = 0$.
 For the third term, $0 \times 16^0 = 0 \times 1 = 0$.

Sum the values Now we add up the values calculated from each term: $$ 256 + 0 + 0 = 256 $$

Final Result Thus, the decimal representation of the hexadecimal number $100$ is $256$.
The decimal representation of the hexadecimal number $100$ is $256$.
More Information
Hexadecimal is a base16 number system that uses digits 09 and letters AF to represent values. Each digit's position represents a power of 16, which can make conversions to decimal quite interesting and useful in computer science.
Tips
 Confusing the powers of 16: Ensure each digit is multiplied by the correct power of 16 based on its position.
 Incorrectly adding up the terms: Doublecheck your arithmetic to avoid mistakes in summation.
