For each flow diagram below, investigate whether the output numbers of the flow diagram will be • odd numbers in all cases or • even numbers in all cases or • odd numbers in some cases, even numbers in other cases. Give examples to support your answers. (a) any odd number × 3 + 1 (b) any even number × 3 + 1 (c) any odd number × any odd number + 1 (d) any even number × any odd number + 1 (e) any even number × any even number + 1 3. In each case, investigate whether the statement is true or false. Give examples to demonstrate your answers. (a) An odd number times an odd number is always an odd number. (b) An even number times an even number is always an even number. (c) An even number times an odd number is always an odd number. (d) Any multiple of an even number is even. (e) Any multiple of an odd number is odd. 4. How many of all the multiples of 3, smaller than 1 000, are odd numbers? 5. How many of all the multiples of 7 are odd numbers? 6. (a) Write all the prime numbers bigger than 60 but smaller than 70. (b) Write all the prime numbers bigger than 40 but smaller than 50. 7. Investigate whether the statement below is true. Then write a paragraph that will convince the reader that what you say is true. If an odd number smaller than 100 is not a prime number, it is a multiple of 3 or 5 or 7.
