- 1) Calculer : A = 10 + 1,5 - 4 - 1,5 ; B = - 8 - 2+ 4; C = -3 x 2 - 7 X (-2) - 1 D = 9+(-3) x 5 = 3; E = 12 – 6= (-3) X 4 ; F = 4 + 2 x (3-7) G = [20 - (15 + 2)] = (-3) + 3 H = 30 - [10 + (20 – 10 = 5) = 9] (-2)

A= 11,5-1,5-4
10-4 =6
B= -6+4 = -2
C= -6 + 14 - 1 = 7
Pour la suite je ne comprends pas si c’est un x ou un fois utilise photomath comme appli ca detaille les calculs et tout

Bonjour

A = 10 + 1,5 - 4 - 1,5

= 11,5 - 5,5

= 6

B = -8 -2 +4

= -10 + 4

= -6

C = -3 2-7 (-2) - 1

= -6 + 14 -1

= -7 + 14

= 7

D = 9+(-3) x 5+3

= 9 -3 X 5 + 3

= 9 -15 + 3

= 12 - 15

= -3

E = 12 - 6+(-3) x4

= 12 -6 -3 X 4

= 12 -6 -12

= -6

F = 4 + 2 x (3-7)

= 4 + 2 X -4

= 4 -8

= -4

H = 30 - [10 + (20 - 10 ÷ 5) ÷ 9] ×(-2)

= 30 - ( 10 + (20 -2) /9) X -2

= 30 - ( 10 + 18/9) X -2

= 30 - (10 +2 X -2)

= 30 - (10 -4)

= 30 -6

H = 24
