Number systems also provide a way to represent negative numbers in digital electronics. One common method is using the two's complement representation. In the two's complement system, the most significant bit (MSB) is used to indicate the sign of the number, with 0 representing a positive number and 1 representing a negative number. This representation allows for efficient addition and subtraction operations in digital circuits. In addition to the fundamental number systems, digital electronics also employ various arithmetic operations on these number systems, including addition, subtraction, multiplication, and division. These operations are carried out using dedicated logic circuits such as adders, subtractors, and multipliers, which manipulate the binary representations of numbers.
