Question

**Title: Understanding Two’s Complement Representation in 8-bit Binary System**

Assume numbers are represented in 8-bit two's complement representation. Show the calculation of the following:

a. \(6 - 13\)

b. \(-6 - 13\)

---

**Explanation:**

In two's complement representation, positive numbers are represented as usual in binary, whereas negative numbers are represented by inverting the binary digits of the positive equivalent and adding one to the result. This representation allows for simple binary arithmetic and is commonly used in computer systems for signed number operations.

To solve these computations, first convert the numbers to their 8-bit binary representations, perform the subtraction in binary by adding the two’s complement of the second number, and interpret the result.

**Example Calculation:**

1. **\(6 - 13\)**:
- Convert \(6\) and \(13\) to binary.
- Find the two’s complement of \(13\).
- Add the binary of \(6\) to the two’s complement of \(13\).

2. **\(-6 - 13\)**:
- Convert \(-6\) and \(13\) to binary.
- Find the two’s complement of both numbers.
- Add the two’s complement of \(-6\) to the two’s complement of \(13\).

These operations illustrate how subtractions are efficiently handled in binary using two’s complement, simplifying arithmetic operations within digital systems.
