1. Look at binary representations of the even numbers we did earlier, such as 86,18 and 50. What do they all have in common? 2. Look at the odd numbers like 35 and 101. What do their binary representations have in common? 3. Let's say you've just written down the binary form of some number x. What will happen to the value of the number if we put a " 0 " at the beginning of x ? 4. What would happen if we put a " 0 " at the end? 5. If a binary number has all is in it (e.g.111, 1111, 11111), what kind of number is this? Yes it would be odd; yes it will have all 15 - be more specific about the pattern
