(+8)+(-23)+(-8)+(+23)
0.36+(-0.74)+0.5+(-0.6)+0.24
(-3/7)+(+1/5)+(+2/7)+(-1 1/5)

数学有理数加减混合运算(+8)+(-23)+(-8)+(+23) 0.36+(-0.74)+0.5+(-0.6)+0.24 (-3/7)+(+1/5)+(+2/7)+(-1 1/5)
(+8)+(-23)+(-8)+(+23)=8-23-8+23=0
0.36+(-0.74)+0.5+(-0.6)+0.24=(0.36+0.24-0.6)+0.5-0.74=-0.24
(-3/7)+(+1/5)+(+2/7)+(-1 1/5)=(-3/7 + 2/7)+(1/5 - 1 1/5)=-1/7-1

1.
8-23-8+23=0
2.
