The purpose of this article is to design and analysis various adder and subtractor circuits. During the first part, it was investigated how to construct a half adder/Subtractor circuit. In this part, one XOR and one AND chip were used. During the second part, it was used XOR, AND and OR chips to implement a full adder/ subtractor. Finally, It was implemented a circuit which was capable to add or subtract two 3-bit numbers using three full adders and XOR chips.
