1. 看谁算得又快又准。
3.3 - 2.1 =
1.2 - 1.1 =
0.3 + 6.9 =
1.5 + 4.5 =
6.9 + 1.3 =
4.6 + 5.4 =
0.3 + 6.7 =
8.6 - 6.3 =
8.8 - 3.1 =
8.5 - 7.5 =
1.2 + 8.1 =
9.5 - 8.5 =
7.5 + 1.5 =
8.9 + 0.6 =
1.6 + 8.4 =
8.8 - 0.9 =
5.1 - 3.9 =
7.7 - 5.7 =
5.3 - 4.2 =
1.6 + 3.4 =
6.1 + 0.8 =
2.6 + 1.7 =
7.8 - 6.9 =
9.8 - 9.8 =
8.9 - 8.1 =
5.3 + 2.7 =
4.6 + 5.2 =
2.1 + 2.6 =
3.8 - 2.8 =
4.8 - 3 =
