👉 Unsigned arithmetic is a mathematical system where numbers are represented without the concept of negative values, meaning only non-negative integers (0 and positive numbers) are used. In this system, operations like addition and multiplication are defined such that the result can be any non-negative number. For example, adding 5 and 3 results in 8, and multiplying any two non-negative numbers yields a positive product. This contrasts with signed arithmetic, which includes negative numbers and uses different rules for handling subtraction (e.g., \( a - b \) is equivalent to \( a + (-b) \)). Unsigned arithmetic simplifies calculations and is commonly used in hardware implementations, such as in computer processors, where it ensures predictable and efficient operations without the complexity of handling negative values.
