The calculation of rational number in junior high school 1)23-17-{-7}+{-16}(2)(+24)+(-14)+(-16)+(+8) (3)2/3-1/8-(-1/3)+(-3/8)(4)(41)+(-23)+(-34)+0 (5)1/2+(-2/3)-(-4/5)-(-1/2)

23-17-{-7}+{-16}=23-17+7-16=-3(+24)+(-14)+(-16)+(+8)=24-14-16+8=22/3-1/8-(-1/3)+(-3/8)=2/3-1/8+1/3-3/8=1/2(41)+(-23)+(-34)+0=41-23-34=-161/2+(-2/3)-(-4/5)-(-1/2)=1/2-2/3+4/...
