答案:
解析:这些题目都是基础的加法运算题目,考查的是对10以内数字的加法掌握。根据加法的性质,一个加数等于和减去另一个加数。我们只需要将每道题的等式两边进行相应的减法运算,就可以求出空缺的数字。

答案:
解析:这些题目都是基础的加减法运算,主要考查学生对10以内数的加减法的掌握。
答案:
6 + 3 + 1 = 10
3 + 4 + 3 = 10
2 + 8 - 4 = 6
10 - 6 - 4 = 0
10 - 8 - 1 = 1
9 - 4 - 4 = 1
1 + 1 + 8 = 10
1 + 7 - 6 = 2
4 - 1 - 2 = 1
9 - 1 - 4 = 4
5 + 2 - 5 = 2
9 + 1 - 7 = 3
8 + 2 - 6 = 4
9 - 5 - 2 = 2
答案:
6 + 3 + 1 = 10
3 + 4 + 3 = 10
2 + 8 - 4 = 6
10 - 6 - 4 = 0
10 - 8 - 1 = 1
9 - 4 - 4 = 1
1 + 1 + 8 = 10
1 + 7 - 6 = 2
4 - 1 - 2 = 1
9 - 1 - 4 = 4
5 + 2 - 5 = 2
9 + 1 - 7 = 3
8 + 2 - 6 = 4
9 - 5 - 2 = 2
