计算题:|-0.75|+(+3又1/4)-9-(-0.125)+(-5/8)-|-0.125|

:|-0.75|+(+3又1/4)-9-(-0.125)+(-5/8)-|-0.125|
=0.75+3.25-9+0.125-5/8-0.125
=-5-5/8
=-5又5/8有没什么简便方法好像是有的吧0.75+3.25=4 0.125-0.125=0(⊙o⊙)…能有过程吗稍微详细一点拜托了:|-0.75|+(+3又1/4)-9-(-0.125)+(-5/8)-|-0.125|=0.75+3.25-9+0.125-5/8-0.125=(0.75+3.25)-9+(0.125-0.125)-5/8=4-9+0-5/8 =-5-5/8=-5又5/8
