Exercice 1: Opérations sur les entiers relatifs
Simplifier (sans la calculatrice) chacun des nombres suivants :
A = (-7) + 13-6
E = 17+ (-25)
I = 2 + 6x 7
B = 52 + (-11) - 44 F = -(45 + 32)
J = 7 x 8
C = (-37) + (-13) G = 2 x (6 + 7)
K = 9x(-4)
D = (-12) - (-15)=-3 H = (2+6) x 7
L = (-3) x 7
M = (-9) (-8)
N = 11 x 6
O = (-4) x 8
P = (-111) × (-5)
Exercice 2: Diviseurs et multiples

Sagot :

A = (-7) + 13-6

=(-7)+7

=0

E = 17+ (-25)

=-8

I = 2 + 6×7

=2+42

=44

B = 52 + (-11) - 44

=52-55

=-3

F = -(45 + 32)

=-77

J = 7 x 8

=56

C = (-37) + (-13)

=-50

G = 2 × (6 + 7)

=2×13

=26

K = 9x(-4)

=-36

D = (-12) - (-15)

=-12+15

=3

H = (2+6) x 7

=8×7

=56

L = (-3) x 7

=-21

M = (-9) ×(-8)

=72

N = 11 x 6

=66

O = (-4) x 8

=-32

P = (-111) × (-5)

=555
