  2. Expanded Form • Writing a number as the sum of the values of each digit 3 , 5 0 8 = 3,000 + 500 + 8 (3 x 1,000) + (5 x 100) + (8 x 1) 2 7 1 6 0 = 20,000 + 7,000 + 100 + 60 , (2 x 10,000) + (7 x 1,000) + (1 x 100) + (6 x 10)

  3. Expanded Form 4 7 0 6 2 = 40,000 + 7,000 + 60 + 2 , (4 x 10,000) + (7 x 1,000) + (6 x 10) + (2 x 1) (4 x 104) + (7 x 103) + (6 x 101) + (2 x 100) 6 8 , 2 5 0 , 0 0 0 = 60,000,000 + 8,000,000 + 200,000 + 50,000 (6 x 10,000,000) + (8 x 1,000,000) + (2 x 100,000) + (5 x 10,000) (6 x 107) + (8 x 106) + (2 x 105) + (5 x 104)

  4. Standard Form to Number and Word Form • Write significant digits • Change comma to decimal • Name the period indicated by the comma 4 8 , 5 0 0 , 0 0 0 6 7 5 0 , 0 0 0 , 8 5 . million 46 75 . million
