Bonjour pouvez vs m'aider merci Il faut détaillé sachant que a=-2,b=-8,c=11 A)a+b+c= B)a x b+c= C) a+b x c= D) (a + b ) x c= E) ( a - b ) x c - c ( a + b )=

A)a+b+c=  + -2 + -8 +11
A = -2-8 +11
A = -10 +11
A = 1

 B)a x b+c= -2 x -8 + 11
b = +16+11
b = 27

 C) a+b x c=  -2 -8 x 11
c = -2  - 88
c = -90

D) (a + b ) x c=
d =(-2-8) x 11
d = -10 x11
d = - 110

E) ( a - b ) x c - c ( a + b )=
(-2+8) x 11  -11(-2-8)
6x11 - 11(-10)
66 + 110
176

A = -2 + -8 +11 = -10 + 11 = 1
B = -2x-8 + 11 = 16+11 = 27
C = -2 + -8x11 = -2 -88 = -90
D  = (-2+ -8)x11 = -10 x 11 = -110
E = (-2- -8)x11-11(-2+-8) = (-2+8)x11-11x-10 = 6x11+110 = 66+110 = 176
