How do adders behave?

Adders are digital circuits used to perform addition of binary numbers. They can be classified into different types, such as half adders and full adders. A half adder adds two single-bit binary numbers and produces a sum and a carry output, while a full adder takes into account an additional carry input from a previous addition. Adders are fundamental components in arithmetic logic units (ALUs) and are crucial for various computing operations.
