奥数计算题：（0.37+0.29+2）×﹙0.37＋0.29＋0.17﹚－﹙2＋0.37＋0.29＋0.17﹚×﹙0.37＋0.2﹚奥数计算题：（0.37+0.29+2）×﹙0.37＋0.29＋0.1
奥数计算题：（0.37+0.29+2）×﹙0.37＋0.29＋0.17﹚－﹙2＋0.37＋0.29＋0.17﹚×﹙0.37＋0.2﹚
奥数计算题：（0.37+0.29+2）×﹙0.37＋0.29＋0.17﹚－﹙2＋0.37＋0.29＋0.17﹚×﹙0.37＋0.2﹚
奥数计算题：（0.37+0.29+2）×﹙0.37＋0.29＋0.17﹚－﹙2＋0.37＋0.29＋0.17﹚×﹙0.37＋0.2﹚
（0.37+0.29+2）×﹙0.37＋0.29＋0.17﹚－﹙2＋0.37＋0.29＋0.17﹚×﹙0.37＋0.2﹚
=(0.37+0.29+2)×(0.37＋0.29＋0.17)-(2＋0.37＋0.29)×(0.37+0.2)-0.17×（0.37+0.2）
=（0.37+0.29+2）×(0.37+0.29+0.17-0.37-0.2)-0.17×0.57
=2.66×0.26-0.17×0.57
=0.6916-0.0969
=0.5947
直接算呗，还需要什么特殊方法吗？
这是一道典型的字母替代法的计算题。从这方面入手考虑。
