a) = -4*[8-10-28]:15=-4*(-30):15=120:15=8
b) = 5+(-4)*(-4)-3*(-12):6=5+16-(-36):6 = 5+16+36:6=5+16+6=27
c) = -[-7-8]:[-4+30:10-2]-7= -[-15]:[-4+3-2]-7 = 15: [-3] - 7 = -5-7=-12
Gdzie niby błąd? ;]
100% dobrze :)
Więc tak:
a) -(-(-4)) * [8- (-5) * (-2) + (-4) * 7] : [ - (-4) + 11] = (-4) * [-2 + (-28) ] : [4+11] = (-4) * (-30) : 15 = 120: 15 = 8
b) - (-(-(-5))) + (-4) * (8-12) - (-(-3)) * (-12) : (-(-6)) = - (-5) + 16 - (-36) : 6 = 5+16 - (-6) = 27
c) - [-(-10 +17) - 8] : [-4 +3 * (-5) * (-2) : 10 - 2] + 9-7) = - [-15] : [-4 + 3 -2] + (-7) = 15: (-3) - 7= -5 -7 = -12
Mam podobny podręcznik :D Powodzenia!
PS Mój poprzednik w ostatnim ma błąd :P MOJE odpowiedzi są na 100% dobrze :D
