Bonjour
Besoin d’un petit coup de main en mathématiques
Merci
Effectue les calculs suivants, en détaillant toutes les étapes.
A = -3 -2 × (-4)
B = -6 x 2 + 10
C = -5 x 3 + (-12) × (-3)
D = 9x(5-7)
E = 3 - [7-(-1) x (4-9)]
F = (-7-2) × (5-8)
G = (-7-2) : (5-8)
Merci

bonjour
A = -3 -2 × (-4)
A = - 3 + 8 = 5
B = -6 x 2 + 10
B = - 12 + 10 = - 2
C = -5 x 3 + (-12) × (-3)
C = - 15 + 36 = 21
D = 9x(5-7)
D = 45 - 63 = - 18
E = 3 - [7-(-1) x (4-9)]
E = 3 - [ 7 + ( 1* - 5 ) ]
E = 3 - ( 7 - 5 )
E = 3 - 2 = 1
F = (-7-2) × (5-8)
F = - 9 * ( - 3 ) = 27
G = (-7-2) : (5-8)
g = ( - 9 ) : ( - 3 )
G = 3

Bonjour
Explications étape par étape :
Petit coup de pouce !
A = -3 -2 × (-4)
A = -3 + 8 = 5
B = -6 x 2 + 10
B = -12 + 10 = -2
C = -5 x 3 + (-12) × (-3)
C = -15 + 36
C = 21
D = 9 x (5-7)
D = 9 X -2
D = -18
E = 3 - [7-(-1) x (4-9)]
E = 3 - ( 7 + 1 X -5)
E = 3 - ( 7 -5)
E = 3 -2
E = 1
F = (-7-2) × (5-8)
F = -9 X -3
F = + 27
G = (-7-2) : (5-8)
G = -9 : -3
G = + 3
