  51. 51. Again, a similar technique is used when there is just a zero in the units column, for example 570 – 124 First, an adjustment is made from the tens to the units 500 _ 60 70 10 0 100 20 4 400 + 40 + 6 To complete the sum, add up the 3 answers to give a final total. = 446 When this can be performed confidently, it can be simplified to a standard written method: 6 10 5 7 0 _ 1 2 4 Firstly, an adjustment is made from the tens to the units
  52. 52. Again, a similar technique is used when there is just a zero in the units column, for example 570 – 124 First, an adjustment is made from the tens to the units 500 _ 60 70 10 0 100 20 4 400 + 40 + 6 To complete the sum, add up the 3 answers to give a final total. = 446 When this can be performed confidently, it can be simplified to a standard written method: 6 10 5 7 0 _ 1 2 4 6 The units can then be subtracted,
  53. 53. Again, a similar technique is used when there is just a zero in the units column, for example 570 – 124 First, an adjustment is made from the tens to the units 500 _ 60 70 10 0 100 20 4 400 + 40 + 6 To complete the sum, add up the 3 answers to give a final total. = 446 When this can be performed confidently, it can be simplified to a standard written method: 6 10 5 7 0 _ 1 2 4 4 6 The units can then be subtracted, followed by the tens
  54. 54. Again, a similar technique is used when there is just a zero in the units column, for example 570 – 124 First, an adjustment is made from the tens to the units 500 _ 60 70 10 0 100 20 4 400 + 40 + 6 To complete the sum, add up the 3 answers to give a final total. = 446 When this can be performed confidently, it can be simplified to a standard written method: 6 10 5 7 0 _ 1 2 4 4 4 6 The units can then be subtracted, followed by the tens and finally the hundreds
