Binary Numbers We are very familiar and comfortable with denary numbers (base 10), that is the number system that we are using daily, like year 2009; RM3535.00; 42 litres of petrol; ……. All these numbers use the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9; have you ever ask or think about “What happen after 9?” We have 10, isn’t it? We say, after 9, we write ‘0’ and carry forward ‘1’. What we do is …… 9 19 29 + 1 + 1 + 1 10 20 30 Similarly, a number system of base 8 will use only the digits 0, 1, 2, 3, 4, 5, 6, and 7 [ Note that the digit ‘8’ never appear in the system!] It is also the same for number system of base 5, the digits used are 0, 1, 2, 3, and 4. See how a number system of base 5 works ………. 4 5 14 5 24 5 34 5 + 1 5 + 1 5 + 1 5 + 1 5 10 5 20 5 30 5 40 5 What happen when 44 5 + 1 5 ?? 44 5 + 1 5 100 5 [Note that whenever the sum is 5, we DON’T write 5 but We write ‘0’ and carry forward ‘1’] Any problem understanding this process of addition?? I’ll show some examples for base 5 additions ….
