DPP Bit S can be used to practice the multiplication and division facts.

  1. 9 × 6 = 54, 6 × 9 = 54,
    54 ÷ 9 = 6, 54 ÷ 6 = 9
  2. 6 × 5 = 30, 5 × 6 = 30,
    30 ÷ 6 = 5, 30 ÷ 5 = 6
  3. 8 × 4 = 32, 4 × 8 = 32,
    32 ÷ 8 = 4, 32 ÷ 4 = 8
  4. 10 × 5 = 50, 5 × 10 = 50,
    50 ÷ 5 = 10, 50 ÷ 10 = 5
  5. 9 × 7 = 63, 7 × 9 = 63,
    63 ÷ 9 = 7, 63 ÷ 7 = 9
  6. 6 × 8 = 48, 8 × 6 = 48,
    48 ÷ 6 = 8, 48 ÷ 8 = 6
