  • Use zero: 400 x 700 =
    280 000
  • Expanded form method: 6231 x 3 =
    (6000x3) + (200x3) + (30x3) + (1x3) = 18000 + 600 + 90 + 3 = 18 693
  • Use Zero: 50 x 1200 =
    60 000
  • Use zero: 60 x 300 =
    18 000
  • Expanded form method: 356 x 3 =
    (300x3) + (50x3) + (6x3) = 900 + 150 + 18 = 1068
  • Expanded form method: 539 x 5 =
    (500x5) + (30x5) + (9x5) = 2500 + 150 + 45 = 2695
  • Use doubling: 432 x 2
    432 + 432 = 864
  • Expanded form method: 697 x 4 =
    (600x4) + (90x4 ) + (7x4) = 2400 + 360 + 28 = 2788
  • Use doubling: 323 x 2 =
    323 + 323 = 646
  • Expanded form method: 405 x 6 =
    (400x6) + (00x6) + (5x6) = 2400 + 0 + 30 = 2430
  • Use doubling: 546 x 2 =
    546 + 546 = 1092
