-7+(+7)-(-15)-1= -2.8-6.2+(-3.4)-(-5.6)= ()+ -3.6=0.36.这个数是.(--7+(+7)-(-15)-1=-2.8-6.2+(-3.4)-(-5.6)=()+ -3.6=0.36.这个数是.(-14)-(+5)=-9错哪里了.
-7+(+7)-(-15)-1
=-7+7+15-1
=22-8
=14


-2.8-6.2+(-3.4)-(-5.6)
=-2.8-6.2-3.4+5.6
=5.6-(2.8+6.2+3.4)
=5.6-12.4
=-6.8


()+ -3.6=0.36.这个数是.
0.36-(-3.6)
=0.36+3.6
=3.96
答:这个数是3.96.


(-14)-(+5)=-9错哪里了.
(-14)-(+5)
=-14-5
=-19
