Bonjour excusez de vous déranger par ce gros devoir mes depuis tu ta l’heure je n’y arrive merci de me guider sur la bonne voie.
1.Effectuer les calculs suivants en détaillant les étapes.
A = (–3) + (–4) × (–5)B = –30 (–4 + 6)
C = 5 – (–4) × (–4)D = 5 – 4 × (–4)
E = (–8) – [8 – (–2)] + (–3)F = 3 – 4 × (–5) × (–5)
G = 12 – 62H = (–5)2 + 13
I = –42 + 21J = (–2) × (–5) – (–5)2
K = (–5) × (–3) – 4 × (–6) – 1
L = 6 × (–2) – 3 × (–3) × (–1) × (–2)

Sagot :

Bonjour,

A = (–3) + (–4) × (–5)=

-3*20 = -60

B = –30 (–4 + 6)=

-30* 2 = -60

C = 5 – (–4) × (–4)=

5*-16 = -80

D = 5 – 4 × (–4)=

5* 16 = 80

E = (–8) – [8 – (–2)] + (–3)=

(-8)(10) -3=

-80 -3 = -83

F = 3 – 4 × (–5) × (–5)=

3 +20*-5 =

3-100 = -97

G = 12 – 62 = -50

H = (–5)2 + 13= -10+13 = 3

I = –42 + 2= -40

J = (–2) × (–5) – (–5)2=

10 +10 = 20

K = (–5) × (–3) – 4 × (–6) – 1=

15 +24 -1 = 38

L = 6 × (–2) – 3 × (–3) × (–1) × (–2)=

-12 +9 *2=

-12 +18 = 6
