求40道有理数加减混合运算题。。看好了，是加减法！

(32)+56-68

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

(－32）＋68＋（－29）＋（－68）＝

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

[-4/9]+[-3/5]-[+11/8]+[+5/9]+[-1/8]+[-0.4]=

（－21）-251＋21＋（－151）＝

[-18]-58+[-52]+60=

[-3]+[-2]+[-1]-89+1+2=

(-8)-(-1)+85

45+(-30)-45-30=15

-1.5-(-11.5)+(-1.5)+11.5

-1/4-(-1/2)

-1/4+1/2+5/2

15-[1-(20-4)]15-(1-16)-15-(-15)-15+15-40-28-(-19)+(-24)+(-40)-28+19-24
22.54+(-4.4)+(-12.54)+4.4=22.54-4.4-12.54+4.4

[-|98|+76+(-87)]+23[56+(-75)-(7)]-(8+4+3)

-2/9-7/9-56

[2/3-4-1/4-(-0.4)]/1/3+2

22+(-4)+(-2)+4+3

-2-8-8+1/2+8/1/8

(2/3+1/2)/(-1/12)+(-12)

(-28)/(-6+4)+(-1)

2/(-2)+0/7-(-8)+(-2)

(1/4-5/6+1/3+2/3)/1/2
