(0.8-0.1)×(7-5.99)÷0.01
=0.7×(1.01×100)这一步
=0.7×101
=70.7
[0.15＋﹙3.74-1.8﹚]÷0.11×40.5
=（0.15+1.94）÷0.11×40.5
=（2.09÷0.11）×40.5这一步
=19×40.5
=（20-1）×40.5 这一步
=810-40.5
﹙73.45－37.54＋34.75﹚÷0.02
=（73.45+34.75-37.54）÷0.02 加法交换律
=（108.2-37.54）×50
【=108.2×50-37.54×50=5410-1877=3533】这一步
=70.66×50
=3533
这些题目，基本不能简算。。。

假设条件在短路的实际计算中， 为了能在准确范围内迅速地计算短路电流， 通常采取以下简化假设。（1）不考虑发电机的摇摆现象。（2）不考虑磁路饱和，认为短路回路各元件的电抗为常数。（3）不考虑线路对地电容， 变压器的磁支路和高压电网中的电阻， ...
