Binary Addition and Representation

The video tutorial explains how to add two 8-bit binary integers, starting with an introduction to binary addition. It covers the basic rules of binary addition, such as how to handle carries and the concept of overflow. The tutorial includes several examples, demonstrating the addition of different pairs of numbers: 85 and 170, 43 and 74, 59 and 124, and finally 95 and 222, which results in an overflow. The video emphasizes the importance of understanding these concepts for GCSE exams.
