It is crucial that you understand how the individual half adder works before watching this video. This video can be found here:    • Understanding the Half Adder   We now know how to build a half adder and how they operate. We will now look at how to use them and implement them in circuits together. Since a half adder can only add two bits together, it is best to use them for incrementing a number. Two examples of using half adders to increment a 4-bit number are used in this video.
