1. 看谁算得又快又准。
7.5 - 6.6 =
5.8 - 3.9 =
3.1 + 3.6 =
6.1 - 4.9 =
0.5 + 2.9 =
4.6 + 2.2 =
2.6 + 4.4 =
5.6 + 0.4 =
1.2 + 5.5 =
1.3 + 7.7 =
7.1 + 2.3 =
2.5 + 3.2 =
3.5 + 5.2 =
4.2 + 5.8 =
9.7 - 4.8 =
6.3 + 3.7 =
7.8 - 6.9 =
4.3 - 3.7 =
5.6 + 2.8 =
2.2 - 1.7 =
3.1 + 2.5 =
9.8 - 7.9 =
4.4 + 2.3 =
8.8 - 5.8 =
2.6 + 4.6 =
8.9 - 7.7 =
3.6 + 2.6 =
4.8 - 3.9 =
2.2 + 7.8 =
6.2 - 4.7 =
