What is the result when adding the high-order and low-order nibbles together?

When adding the high-order and low-order nibbles together, the correct outcome is indeed the total obtained from both nibbles. In binary representation, a nibble consists of four bits, and when you combine the values of the high-order and low-order nibbles, you are mathematically adding these two groups of bits.

Consider that each nibble can represent values from 0 to 15 in decimal. Therefore, when you perform the addition operation on these two nibbles, you are calculating a total value that reflects their combined significance. This sum can be useful in various applications, such as computing checksums, performing arithmetic operations in programming, or setting flags in control registers.

The maximum value of a nibble, which is often 15 (binary 1111), is not the result of adding the two nibbles together, but rather the highest possible single nibble value. The statement about only the high-order value ignores the contribution from the low-order nibble. Lastly, while the binary equivalent of the total represents the result of the addition, it doesn't directly state the total but refers to the format of the representation.

In summary, the focus on obtaining the direct sum encompasses the complete process of combining the values
