(-8-a)+(a+23)= -8 -a+a+23=23-8=15
(1.3+m)+(-4-m)=1.3+m-4-m=1.3-4= - 2.7
(p-m+k)+(-p+m+k)=p-m+k -p+m+k=k+k=2k
(3.7-2.6+4.2)+(-12.5+2.6-4.2)=3.7 - 2.6+4.2 -12.5+2.6 -4.2=3.7 - 12.5= - 8.8

(-8.4+a)-(a+14.9)= - 8.4+a - a-14.9= - 23.3
(42 -b) -( -b+36.4)=42 - b + b -36.4=5.6
(m-n)-(-n+m-p)=m-n+n-m+p=p
(-2.2+4.9-c)-(4.9-c-1.3)= -2.2+4.9 -c -4.9+c+1.3= - 0.9
