  • Standard form is used to show how large or small a number is
  • The power of ten in standard form helps determine the size of the number
  • The power of ten is sometimes called the order of magnitude
  • Numbers in standard form can be ordered by the size of their indices and coefficients
  • In the example, the powers of ten are ordered from smallest to largest
  • The numbers are then written in order using their powers of ten
  • The numbers with the same power of ten are ordered by their coefficients
  • The final answer is the numbers written in standard form from smallest to largest
