1. 看谁算得又快又准。
9.9 + 0.1 =
1.3 - 1.2 =
7.7 - 6.6 =
0.3 - 0.2 =
7.5 + 2.1 =
1.8 + 2.4 =
7.6 + 1.4 =
2.4 - 1.5 =
5.2 - 5.1 =
4.8 - 2.1 =
3.6 + 5.2 =
6.3 + 0.2 =
2.2 - 1.3 =
2.7 - 1.1 =
8.7 - 4.5 =
6.5 + 0.5 =
5.9 + 3.1 =
5.5 + 1.5 =
6.2 + 1.3 =
0.6 - 0.2 =
8.2 - 2.2 =
3.2 - 0.1 =
8.2 + 0.8 =
5.6 + 3.4 =
0.6 - 0.5 =
9.1 - 8.1 =
5.7 + 4.1 =
8.9 + 0.4 =
2.5 + 7.5 =
4.7 - 2.9 =
