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。
