(-32)+68+(-29)+(-68)=

(-21)+251+21+(-151)=

12+35+(-23)+0=

(-6)+8+(-4)+12 =

27+(-26)+33+(-27)

12+35+(-23)+0=

39+[-23]+0+[-16]=

[-18]+29+[-52]+60=

[-3]+[-2]+[-1]+0+1+2=

[-301]+125+301+[-75]=

[-1]+[-1/2]+[+3/4]+[-1/4]=

[-7/2]+[+5/6]+[-0.5]+4/5+19/6=

[-26.54]+[-6.14]+18.54+6.14=

1.125+[-17/5]+[-1/8]+[-0.6]=

( -23)-(-27)—27

(-1)+2+(-3)-(-4)

26+(-73)

(-84)+(-49)

7.1+(-2.04)

4.23+(-7.57)

(-7/3)+(-7/6)

9/4+(-3/2)

3.75+(2.25)+5/4

-3.75+(+5/4)+(-1.5)

(-17/4)+(-10/3)+(+13/3)+(11/3)

(-1.8)+(+0.2)+(-1.7)+(0.1)+(+1.8)+(+1.4)

(+1.3)-(+17/7)

(-2)-(+2/3)

|(-7.2)-(-6.3)+(1.1)|

(-5/4)-(-3/4)|-|1-5/4-|-3/4|)

–3-[4-(4-3.5×2 )]×[-2+(-3) ]

8+(- )- 5- (- 0.25)

(-3 )÷(4 -12 )÷(-2 )×(-1 )

(-2)14×(-3)15×(-1 )14
