2. 1 Data Storage 1.5 The Binary System Binary Notation Binary Addition Fractions in Binary Pearson Custom: Computer Science, Data Representation and Machine Concepts

3. 1 Data Storage Binary Notation Recall How to convert binary notation to decimal notation How to convert decimal notation to binary notation Convert 11010012 to decimal notation Convert 12310 to binary notation

4. 1 Data Storage Binary Addition Binary addition rule 0 + 0 = 0 1 + 0 = 1 0 + 1 = 1 1 + 1 = 10 1 + 1 + 1 = 11 10010011 + 111011

5. 1 Data Storage Binary Addition Binary addition rule 0 + 0 = 0 1 + 0 = 1 0 + 1 = 1 1 + 1 = 10 1 + 1 + 1 = 11 1 10010011 + 111011 0

6. 1 Data Storage Binary Addition Binary addition rule 0 + 0 = 0 1 + 0 = 1 0 + 1 = 1 1 + 1 = 10 1 + 1 + 1 = 11 11 10010011 + 111011 10
