1. Rozwiąż równania
a) (-20+8+(-4)):8-(6+(-4)-10)*4+3*((-1/2)-2.4):(-0.6)=
b) (-5)^3+(-5)*(-4)-20:(-4)+(-2)^2 *5=
2.Porównaj wartości podanych wyrażeń
1.(-5/6)*2/3 ........... 4/9:(-5/6)
2.0.2*5+(-4):0.5........ 0.6*(-5)-1:0.2
3.1 3/4 :14.......... (-0.5):(-10)
4.5:(-6).......(-8):12

Zad 1
a) -16 : 8 - (-8)*4 + 3*(-2.9) : (-0.6) =
-2 + 32 + 8.7 : (-0.6) =
30 + (-14.5) = 15,5
b) -125 + 20 - (-5) + 20 = -105 + 5 + 20 = -80
Zad 2
a) - 10/18 > - 24/45
b) 1 - 8 ....... -3 - 5
-7 > -8
c) 1/8 ..... 0.05
0.125 > 0.05
d) - 5\6 ...... - 8/12
-5\6 < -4\6
