Bonjour


on donne :

a = -2 ; b = 4 ; c = 3 ; d = -1


calculer :


A = a - b + c - d

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

A = -6 + 3 + 1

A = -6 + 4

A = -2


B = a - (b + c) - d

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

B = -2 - 7 + 1

B = -9 + 1

B = -8


C = (b - a) - (c + d)

C = (5 - (-2)) - (3 + (-1))

C = (5 + 2) - (3 + 1)

C = 7 - 4

C = 3
