1. 看谁算得又快又准。
2.1 + 4.7 =
7.6 + 1.5 =
2.5 + 5.2 =
0.6 + 1.4 =
5.3 - 0.9 =
7.5 - 2.7 =
6.6 - 2.4 =
4.5 + 3.2 =
6.2 - 1.8 =
5.9 - 3.1 =
8.5 - 1.3 =
1.1 + 6.6 =
2.5 + 7.3 =
6.2 - 3.5 =
5.8 - 2.4 =
5.6 + 2.7 =
2.1 + 4.5 =
1.9 + 7.4 =
3.1 + 3.9 =
3.1 + 5.9 =
6.9 - 0.7 =
0.8 + 7.8 =
5.5 - 4.4 =
3.8 + 4.5 =
2.7 + 6.3 =
2.6 + 4.5 =
3.1 + 3.1 =
4.6 + 5.7 =
0.9 + 7.6 =
1.2 + 2.1 =
