-8+(-12)-(-6)= 16+(-17)-(-22)+(-5)-1= 12-(-6)+(-18)-(-3)= -4+(-7)-(4)-3= -7-9+(-6)-(-9)=

Musisz pamiętać, że - i - daje +, + i - daje -, + i + daje + więc: -8+(-12)-(-6)= -20 + 6 = -14 16+(-17)-(-22)+(-5)-1= -1 - (-27) -1= 25 12-(-6)+(-18)-(-3)= 18 + (-15)= 3 -4+(-7)-(4)-3= -13 - 7= -20 -7-9+(-6)-(-9)= -16 - 6 + 9 = - 16 + 3= -13

-8+(-12)-(-6)=-8+(-18)=-26 16+(-17)-(-22)+(-5)-1=-1+-27+-1=-29 12-(-6)+(-18)-(-3)=18+(-15)=3 -4+(-7)-(4)-3=-11-1=-12 -7-9+(-6)-(-9)=-16+3=-13

1. -8+(-12)-(-6) = -8-12+6 = -14 2. 16+(-17)-(-22)+(-5)-1 = 16-17+22-5-1 = 15 3. 12-(-6)+(-18)-(-3) = 12+6-18+3 = 3 4. -4+(-7)-(4)-3 = -4-7-7 = -18 5. -7-9+(-6)-(-9) = -7-9-6+9 = -13
