We have three circuits made with NAND, one with the same result of doing an OR, another one to AND and the last one to NOT

First attempt at Half Adder. A half adder is a logical circuit that adds to one bit binary numbers and results into a two digit output.

My first attempt at an full adder. This is a logical circuit that performs an addition operation on three one bit binary numbers. The full adder produces a sum of three inputs and a carry value.
