Sagot :
Bonjour,
A = -6 - 64 ÷ (-12 + 4)
= -6 - 64 ÷ (-8)
= -6 - (-8)
= -6 + 8
= 2
B = (-6 - 9) + (-54 + 6) ÷ (-8)
= -15 + (-48) ÷ (-8)
= -15 + 6
= -9
C = 6 + (-5 - 3) × (8 - 6)
= 6 + (-8) × 2
= 6 + (-16)
= 6 - 16
= -10
Réponse :
Explications étape par étape :c
A = –6–64:(–12+4)
A = –6–64:–8
A = –6–8
A = –14
B = (–6–9)+(–54+6):(–8)
B = –15+(–48):(–8)
B = –15+(-6)
B = -21
C = 6+(–5–3)×(8–6)
C = 6+(–8)×2
C = 6+(–16)
C = (-10)
