10-2*[(-1,6)+(-19,5):(2,05)]=

10-2*[(-1,6)+(-19,5):(2,05)]= 8*[(1,6)+(-9,51)]=8*(-7.91)=(-63.28) Jesli * to razy =) to powinno byc dobrze =)

10-2*[(-1,6)+(-19,5):(2,05)]= 10-2*[(-16/10)+ (-195/10):205/100)]= 10-2*[(-8/5)+ (-39/2:41/20)]= 10-2*[-8/5 +(-39/2 *20/41)]= 10-2*[-8/5 -78/41]= 10-2*(-328/205-390/205)= 10-2*(-718/205)=10+1436/205=10+6 1/205= 16 1/205
