Cześć ,
mam obliczyć działania ,ktróre pan zadał :
ą) (-4) * [ 15 + 3*(-4) ] =.................
b) [-32 - (-30) + (-3) ] *(-6) =.............
c) [18 + (-10) - 20 - (-2) ] : (-2) =...............
d) [-30 - 20 - (-3) + 5 ] : 6 =............................
e) (26-30) + [-9 + (-3)] : (-4) =............................
jak moglibyście to uzupełnić ale nie tak, że np. tylko wynik wpisać ale także równanie :) plliiisssss potrzebne mi na jutro !

ą) (-4) * [ 15 + 3*(-4) ] = (-4) * [15-12] = (-4) * 3 = -12
b) [-32 - (-30) + (-3) ] *(-6) = [-32 + 30 -3 ] *(-6) = [-32 + 30 -3 ] *(-6) = -5 *(-6) = 30
c) [18 + (-10) - 20 - (-2) ] : (-2) = [18 -10 - 20 + 2 ] : (-2) = [18 -10 - 20 + 2 ] : (-2) = -10 : (-2) = 5
d) [-30 - 20 - (-3) + 5 ] : 6 = [-30 - 20 + 3 + 5 ] : 6 = [-30 - 20 + 3 + 5 ] : 6 = -42 : 6 = -7
e) (26-30) + [-9 + (-3)] : (-4) = (26-30) + [-9 -3] : (-4) = (26-30) -12 : (-4) = -4 -12 : (-4) =
= - 4 + 3 = -1
