好的以下是一道三年级的数学口算题目:

23 + 17 =

45 - 19 =

12 + 8 =

56 - 30 =

38 + 7 =

29 - 5 =

15 + 14 =

62 - 27 =

24 + 9 =

51 - 13 =

36 + 6 =

73 - 29 =

18 + 11 =

55 - 16 =

33 + 8 =

48 - 22 =

27 + 7 =

64 - 31 =

22 + 9 =

57 - 24 =

13 + 10 =

58 - 35 =

25 + 14 =

69 - 28 =

31 + 6 =

47 - 21 =

16 + 12 =

63 - 37 =

19 + 8 =

56 - 33 =

解答如下:

23 + 17 = 40

45 - 19 = 26

12 + 8 = 20

56 - 30 = 26

38 + 7 = 45

29 - 5 = 24

15 + 14 = 29

62 - 27 = 35

24 + 9 = 33

51 - 13 = 38

36 + 6 = 42

73 - 29 = 44

18 + 11 = 29

55 - 16 = 39

33 + 8 = 41

48 - 22 = 26

27 + 7 = 34

64 - 31 = 33

22 + 9 = 31

57 - 24 = 33

13 + 10 = 23

58 - 35 = 23

25 + 14 = 39

69 - 28 = 41

31 + 6 = 37

47 - 21 = 26

16 + 12 = 28

63 - 37 = 26

19 + 8 = 27

56 - 33 = 23
