Calcule les expressions suivantes :
A = 3 - 4 x (5 - 2). D = -3+(1-5) X (-6)
B = 3 x 4 - 2 x (4 - 1)
E = 1-2 x 3+4 (-5)

Sagot :

Réponse:

A = -9

B = 6

D = 21

E = -7

Explications étape par étape:

A = 3-4 * (5-2)

A = 3-4 * 3

A = 3-12

A = -9

B = 3*4 - 2*(4-1)

B = 3*4 - 2*3

B = 12 - 6

B = 6

D = (-3) + (1-5) * (-6)

D = (-3) + (-4) * (-6)

D = -3 + 24

D = 21

E = 1-2 * 3+4-5

E = 1-6+3-5

E = -5 +3 -5

E = -2 -5

E = -7
