Пошаговое объяснение:
( -13) + 29+ (-9) + 13 = - 13+13 +29 +( -9)= 0+20=20
(-3)+(-28)+28+7 = (- 28) +28+7 + ( -3)= 0+4=4
-5+(5+(-99)) = - 5 +5 + ( -99)=0+(-99)= -99
(-48+91)+(-91) =-48 +91 +( -91)= - 48+ 0= - 48
(-34+59)+34 = -34 +34 +59= 0+59=59
(47+(-91))+91 =47 + (-91)+91=47+0=47
(-4)+(-2)+22+14 = 22+( -2) + 14 + ( -4)=20 +10= 30
-28+(18+29) = - 28 +18 +29= - 10 +29= 19
-10+(-10+30) = -10 + ( -10) +30= -20 +30 = 10
