Dear students, Assalamu Alaikum. I hope you are well. By watching this video, you will be able to learn the complement of 1 and the complement of 2. Very easily explained. The rule for finding the complement of 2 is to add 1 to the complement of the binary number 1 to get the complement of 2. If anyone still has trouble understanding, let me know in the comments. After finding the complement of 2, you can subtract by adding. That is, to learn subtraction through addition, one has to use the complement of these two. Computer completes the work of subtraction through the complement of 2. Hopefully this video will help you learn subtraction through addition. If you like the class, be sure to let us know in the comments and don't forget to subscribe to the channel to get the classes easily later.
