zad.1 Oblicz :
a) (-6)-2(-4)= -6 - (-8) = -6 + 8 = 2
b) (-10)+5-7 = (-5) + (-7) = -12
c) 5-13-(2) = 5 + (-13) +(-2) = 5 + (-15) = -10
d) 6+(-8)-(-3) = -2 + 3 = 1
e) (-7)+(-12)-6+18= -19 + (-6) + 18 = -25 + 18 = -7
f)25+(-16)-(12)-3 = 25 + (-16) + (-12) + (-3) = 25 + (-31) = -6
zad.2 podaj po pięć liczb , które można wpisać w kratkę:
a) [_]-5>0
6, 7, 8, 9, 10
b) (-5)- [_]>0
-6, -7, -8, -9, -10
c) [_] - (-2) <0
-12, -11, -10, -9, -8
