1. 看谁算得又快又准。
3.5 - 2.9 =
7.8 - 6.5 =
6.8 - 5.9 =
6 - 3.5 =
3.1 + 6.8 =
3.7 + 3.6 =
5.9 - 2.7 =
5.1 + 3.9 =
4.6 + 4.8 =
7.7 - 2.3 =
9.9 - 8.7 =
6.5 + 1.7 =
9.7 - 7.8 =
6.5 - 5.2 =
2.5 - 1.9 =
8.4 - 4.8 =
7.8 - 6.6 =
3.5 - 2.8 =
1.3 + 4.9 =
9.9 - 7.6 =
1.4 + 7.5 =
5.4 + 2.8 =
4.8 + 4.2 =
2.8 + 6.8 =
6.7 + 1.5 =
6.7 - 3.6 =
0.7 + 6.4 =
0.4 + 6.6 =
5.5 - 4.9 =
2.9 + 1.1 =
