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
