Question

13.2+17.5-(+0.8)-(-22)-(-0.5)=
-0.54+(-3.24)=
-1+(-9 /1\31)=
-7.9+(-4.2)=

Answer 1

13,2+17,5-(+0,8)-(-22)-(-0,5)=13,2+17,5-0,8+22+0,5=52,4

-0,54+(-3,24)=-0,54-3,24= - (0,54+3,24)= - 3,78

-1+( -9 1/31)= - 1 - 9 1/31= - (1+9 1/31)= - 10 1/31

-7,9+(-4,2)= - 7,9 - 4,2= - (7,9+4,2)= - 12,1
