EFFECTUER SANS CALCULATRICE
A = (-10 + 12) (-6 +9)
B (-7 +14 )x12
C= [-8-( - 12)] x 19
D = 10 + 8x6 - (- 4 + 6)
E = - 10 + 8 x 6 - 4
F= (-7 + 9 + 3 )x13

j'aimerais des explications merci beaucoup ​​

Bonsoir

Effectuer sans calculatrice :

A = (-10 + 12) (-6 +9)

A = - 2 x 3

A = - 6

B (-7 +14 )x12

B = 7 x 12

B = 84

C= [-8-( - 12)] x 19

C = (- 8 + 12) x 19

C = 4 x 19

C = 76

D = 10 + 8x6 - (- 4 + 6)

D = 10 + 48 - 2

D = 58 - 2

D = 56

E = - 10 + 8 x 6 - 4

E = - 10 + 24 - 4

E = - 14 + 24

E = 10

F= (-7 + 9 + 3 )x13

F = (- 7 + 12) x 13

F = 5 x 13

F = 65.
