  1. 10 less than 34 is 24
  2. 53 – 20 = 33
  3. 11 more than 31 is 42
  4. 11 less than 66 is 55
  5. 62 + 13 = 78
  6. 23 less than 89 is 66
  7. 10 and 40 more is 40
  8. 9 added to 28 gives 37
  9. The sum of 9 and 44 is 53
  10. Reducing 98 by 34 gives 64
  11. 4 and 37 more is 37
  12. Take 35 away from 83. we get 48

E.g.,  47 = 37 + 10

37 + 9 = 46

65 – 30 = 35

67 =  46 + 21

57 = 87 – 30

66 55 = 11                                            36 = 27 + 9

45 + 54 = 99                                            40 + 36 = 76

49 + 26 = 75                                            98 = 48 + 50

56 – 21 = 35                                            57 – 37 = 20

  • Can you do it another way? Say How.

33 + 56 = 30 + 3 + 50 + 6

= 80 + 3 + 6

= 80 + 9 = 89

See if you can do the same with these sums.

37 + 22 = 30 + 7 + 20 + 2

               = 50 + 7 + 2

               = 50 + 9 = 59

73 + 24 = 70 + 3 + 20 + 4

               = 90 + 4 + 3

               = 90 + 7 = 97

56 + 21  = 50 + 6 + 20 + 1

               = 70  + 6 + 1

               =  70 + 7 = 77

56 + 21 = 50 + 6 + 20 + 1

              = 70 + 6 + 1

              = 70 + 7 = 77

 

 

Now work out the steps in your mind.

Write the answers directly in the boxes.

33 + 42 = 75       60 = 33 + 27       55 + 25 = 70

19 + 61 = 80       97 = 34 + 63       67 + 25 = 92

90 = 48 + 42     117 = 53 + 64       72 + 56 = 128

 

Practice Time:-

  1. (i) 345 + 52 = 397 (iv) 643 + 345 = 998

 (ii) 492 + 29 = 521            (v)  750  + 219 = 969

 (iii) 245 + 93 = 338
