问题描述：
1/2乘以负的1/22减去负的1/2加1
答
解:1/2x(-1/22)-(-1/2)+1
=-1/44+1/2+1
=3/2-1/44
=66/44-1/44
=65/44
希望我的回答对你有所帮助!
答
(-1/22)*1/2-(-1/2+1)
=-1/44-1/2
=(-1-22)/44
=-23/44
或，因为不清楚有没有括号
(-1/22)*1/2-(-1/2)+1
=-1/44+3/2
=-1/44+66/44
=65/44
1/2(-1/22-(-1/2)+1)
=1/2(-1/22+33/22)
=32/44=8/11
答
原式=1/2*(-1/22)-(-1/2)+1
=-1/44+1/2+1
=-1/44+3/2
=-1/44+66/44
=65/44
