Explications étape par étape

application de la règle des signes

A = (-5) + ( -3)

A = -5 -3 = -8

B = (+5) + (-3)

B = 5 -3

B = 2

C = (+1) + (+1)

C = 1 + 1

C = 2

D = (-5) + (+2)

D = -5 +2

D = -3

E = (+3) + (-7)

E = 3 -7

E = -4

F = (-3) + (-3)

F = -3 -3

F = -6

Bonjour

a. (- 5) + (- 3) = - 5 - 3 = - 8

b. (+ 5) + (- 3) = 5 - 3 = 2

c. (+ 1) + (+ 1) = 1 + 1 = 2

d. (- 5) + (+ 2) = - 5 + 3 = - 3

e. (+ 3) + (- 7) = 3 - 7 = - 4

f. (- 3) + (- 3) = - 3 - 3 = - 6.
