小学20以内加减法

小学20以内加减法

小学20以内的加减法是基础数学学习的重要组成部分,以下是一些基础的加减法练习题目,你可以帮助孩子们练习:

加法练习

```

8 + 8 = 16

1 + 11 = 12

13 - 3 = 10

1 + 7 = 8

16 + 2 = 18

8 + 6 = 14

13 - 4 = 9

3 + 14 = 17

5 + 4 = 9

19 - 1 = 18

7 + 1 = 8

13 - 2 = 11

8 - 1 = 7

16 - 9 = 7

5 + 6 = 11

6 + 8 = 14

5 + 8 = 13

14 - 9 = 5

12 - 9 = 3

12 - 8 = 4

13 - 6 = 7

9 + 9 = 18

15 - 8 = 7

9 - 3 = 6

13 - 8 = 5

16 - 8 = 8

```

减法练习

```

9 - 3 = 6

17 - 6 = 11

11 - 7 = 4

14 + 0 = 14

17 - 3 = 14

9 - 1 = 8

6 - 5 = 1

7 + 11 = 18

```

混合练习

```

8 + 8 = 16

12 - 5 = 7

16 + 2 = 18

4 + 3 = 7

20 - 2 = 18

9 + 10 = 19

19 - 1 = 18

15 + 5 = 20

6 + 6 = 12

5 + 6 = 11

18 - 2 = 16

10 + 7 = 17

7 + 5 = 12

8 + 10 = 18

7 + 3 = 10

20 - 4 = 16

19 - 4 = 15

15 + 2 = 17

16 - 7 = 9

8 + 5 = 13

20 - 6 = 14

1 + 18 = 19

1 + 13 = 14

7 + 3 = 10

```

练习这些题目可以帮助孩子们熟悉20以内的数字以及加法和减法的基本运算。
