1. 看谁算得又快又准。
7.7 - 4.4 =
2.8 + 1.9 =
4.6 - 3.9 =
5.3 + 3.5 =
9.8 - 7.9 =
7.2 - 2.7 =
2.2 - 1.7 =
8.2 - 6.8 =
8.6 - 6.8 =
3.6 + 1.9 =
1.6 + 7.7 =
9.2 - 4.7 =
2.8 - 1.6 =
9.6 - 8.8 =
6.8 - 3.9 =
2.1 + 1.5 =
6.2 - 5.7 =
5.2 + 4.5 =
8.5 - 1.7 =
9.9 - 7.7 =
3.2 + 2.7 =
7.6 - 6.9 =
6.6 - 4.8 =
1.8 - 0.9 =
4.6 - 3.7 =
3.6 + 2.8 =
2.4 + 1.7 =
4.2 + 2.9 =
8.6 - 7.9 =
1.3 + 0.6 =
