1. 看谁算得又快又准。
6.5 - 5.7 =
8.7 - 6.8 =
6.1 - 3.9 =
8.5 - 7.7 =
7.2 - 3.7 =
2.6 + 3.4 =
6.6 + 1.2 =
6.6 - 5.5 =
1.3 + 7.7 =
4.6 + 3.4 =
4.5 + 3.4 =
2.5 + 4.2 =
2.2 + 6.8 =
2.5 + 6.5 =
6.3 + 2.7 =
1.2 + 4.5 =
5.2 + 2.3 =
3.3 + 5.4 =
3.3 + 2.2 =
3.7 - 2.6 =
0.8 + 3.9 =
8.2 - 5.5 =
3.9 - 2.2 =
2.6 + 5.4 =
2.6 + 2.7 =
4.5 - 3.9 =
4.8 - 2.8 =
9.7 - 8.8 =
9.2 - 7.8 =
8.8 - 7.7 =
