Answer 2

Zad.1
a)strata 6 i strata 7 to strata 13 -6+(-7)=-6-7=-13
strata 60 i strata 30 to strata 90 -60+(-30)=-60-30=-90
c)strata 21 i strata 19 to strata 40. -21+(-19)=-21-19=-40
)strata 70 i xysk 80 to zysk 10 -70+80=10
e)zysk 10 i strata 12 to strata 2 10+(-12)=10-12=-2
f)strata 17 i zysk 15 to strata 2 -17+15=-2
g)zysk 65 i strata 110 to strata 45. 65+(-110)=.65-110=-45
h)strata 3,5 i zysk 7,5 to zysk 4 -3,5+7,5=4

zad.3
oblicz;
a) -12+(-11)=-12-11=-23
