(0.6)+1.7+(0.6)+(-1.7)+(-9)-3-4+19-11+2(-5/12)+1/12+1/5+(-13/15)-(-18)+12-15+(-7)-7.5+4.7-(-8.9)+(-6)-2/3+1/6- 3 又1/2+1
问题描述:
(0.6)+1.7+(0.6)+(-1.7)+(-9)
-3-4+19-11+2
(-5/12)+1/12+1/5+(-13/15)
-(-18)+12-15+(-7)
-7.5+4.7-(-8.9)+(-6)
-2/3+1/6- 3 又1/2+1
答
(0.6)+1.7+(0.6)+(-1.7)+(-9)=-7.8(计算题不要过程吧)
-3-4+19-11+2=3
(-5/12)+1/12+1/5+(-13/15)=-1
-(-18)+12-15+(-7)=8
-7.5+4.7-(-8.9)+(-6)=0.1
-2/3+1/6- 3 又1/2+1=-3
权计算器算的 绝对准确
答
(0.6)+1.7+(0.6)+(-1.7)+(-9)=0.6+0.6+1.7-1.7-9=1.2-9=-7.8-3-4+19-11+2=-7+19-11+2=12-11+2=1+2=3(-5/12)+1/12+1/5+(-13/15)=-4/12-13/15+1/5=-5/15-13/15+3/15=-1-(-18)+12-15+(-7)=18+12-15-7=30-15...
