1) (-14,35)-(-53,5)-(+21,3)-( -16 целых 3/20)=
= -14,35+53,5-21,3+16,15=(53,5+16,15)-(14,35+21,3)= 69,65-35,65=34
2) (-60)-(-15,9)-(+8,2)-(- 23,3)= -60+15,9-8,2+23,3=
=-(60+8,2)+(15,9 +23,3)=-68,2+39,2=-(68,2-39,2)= -29
3) 24,6 +(-35,9)-(-6,5)+(-5,2)= 24,6 -35,9+6,5-5,2= 24,6 +6,5-5,2-35,9=
= ( 24,6 +6,5)-(5,2+35,9)=31,1-41,1=-(41,1-31,1)=-10
4) (-32)-(-13,8)-(+26,3)-(-27,5)= -32+13,8-26,3+27,5=13,8+27,5-(32+26,3)=
= 41,3-58,3= -(58,3-41,3)=-17
