bonjour pouvez vous m'aider svp:
on donne :
a=-2; b=4; c=3; d= - 1
a. Calculer A= a-b + c-d.
b. Calculer B= a-(b+c) - d.
c. Calculer C= (b-a) - (c+d).

Bjr,

A = - 2 - 4 + 3 + 1 = - 6 + 4 = - 2

B = - 2 - (4 + 3) + 1 = - 2 - 7 + 1 = - 9 + 1 = - 8

C = (4 + 2) - (3 - 1) = 6 - 2 = 4

Réponse:

A = -2

B= -8

C= 4

Explications étape par étape:

A = -2-4 + 3-(-1)

A= -6 + 4

A = -2

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

B = -2-7 +1

B = -8

C = (4-(-2)) - (3+(-1))

C = (4+2) - (3-1)

C = 6 - 2

C= 4
