(-8)-(-15)+(-9)-(-12)
-3/2+((-6/1)-(-4/1)-2/1
5/3-2/3+(-4/11)+4/13
要写过程能简便的要简便
-2.5+(-5/1)
0.4-(-4/1)+6/1
3/1-(-6/5)+3/2
3/1+(-5/1)+1+3/2
27-18+(-7)-32
0.5+(-4/1)-(-2.75)+2/1
33.1-(-22.9)+(-10.5)
(-8)-(-15)+(-9)-(-12)
-3/2+((-6/1)-(-4/1)-2/1
5/3-2/3+(-4/11)+4/13
要写过程能简便的要简便
-2.5+(-5/1)= -2/5-5/1= -10/25-10/2= -10/27
0.4-(-4/1)+6/1 =5/2+4/1+6/1 = 60/24+60/15+60/10= 60/49
3/1-(-6/5)+3/2 = 6/2+6/5+6/4 = 6/11
3/1+(-5/1)+1+3/2 = 15/5-15/3+15/15+15/10 = 15/27 = 5/9
27-18+(-7)-32 = 9 -7 -32 = 2 -32 = -30
0.5+(-4/1)-(-2.75)+2/1 = 4/2 - 4/1 + 4/11 + 4/2 = 4/14 = 2/7
33.1-(-22.9)+(-10.5) = 33.1 +22.9 -10.5 =56 -10.5 = 45.5
(-8)-(-15)+(-9)-(-12) = -8 +15 -9 + 12 =7 -9 +12 =10
-3/2+((-6/1)-(-4/1)-2/1 = -12/8 - 12/2 +12 /3 -12/6 = -12/13
5/3-2/3+(-4/11)+4/13 = 5/3 -2/3 - 4/11 +4/13 = 0.6 -1.5 +0.5 = -0.4
0.4-(-4/1)+6/1 =5/2+4/1+6/1 = 60/24+60/15+60/10= 60/49
3/1-(-6/5)+3/2 = 6/2+6/5+6/4 = 6/11
3/1+(-5/1)+1+3/2 = 15/5-15/3+15/15+15/10 = 15/27 = 5/9
27-18+(-7)-32 = 9 -7 -32 = 2 -32 = -30
0.5+(-4/1)-(-2.75)+2/1 = 4/2 - 4/1 + 4/11 + 4/2 = 4/14 = 2/7
33.1-(-22.9)+(-10.5) = 33.1 +22.9 -10.5 =56 -10.5 = 45.5
(-8)-(-15)+(-9)-(-12) = -8 +15 -9 + 12 =7 -9 +12 =10
-3/2+((-6/1)-(-4/1)-2/1 = -12/8 - 12/2 +12 /3 -12/6 = -12/13
5/3-2/3+(-4/11)+4/13 = 5/3 -2/3 - 4/11 +4/13 = 0.6 -1.5 +0.5 = -0.4
