1. 3. is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number.
  2. 6. says how many times to use that number in a multiplication.
  3. 8. is the greatest factor that divides two numbers.
  4. 9. two or more non-zero denominators is the smallest whole number that is divisible by each of the denominators.
  5. 11. numbers is a real number that cannot be expressed as a ratio of integers, i.e. as a fraction.
  6. 12. numbers which follow each other in order, without gaps, from smallest to largest.
