8 + 7 = 15 18 + 7 = 28 + 7 = 38 + 7 =
58 + 7 = 68 + 7 = 78 + 7 = 88 + 7 =
9 + 6 = 19 + 6 = 29 + 6 = 39 + 6 =
4 + 9 = 13 + 9 = 23 + 9 = 33 + 9 = 43
3 + 8 = 11 + 8 = 21 + 8 = 31 + 8 = 41
59 + 7 = 66 + 7 = 76 79 + 7 = + 7 = 96
46 + 7 = 56 + 7 = 66 + 7 = 76 + 7 =
+ 9 = 53 + 9 = 63 64 + 9 = 74 + 9 =

 

Find the sum.

26 + 33 = (20 + 6) + (30 + 3) = (20 + 30) + (6 + 3) = 50 + 9 = 59

43 + 21 = ( + 3) + (20 + ) = (40 + ) + (3 + ) =  + 4 = 64

28 + 51 = ( + 8) + ( + 1) = (20 + 50) + (8 + ) = + 9 = 79

 

Find the difference.

57 - 33 = (50 - 30) + (7 - 3) = 20 + 4 = 24

27 - 12 = (20 - ) + (7 - ) = 10 + = 15
