Bonjour
Calculer à la main.
E = 26 – (-14 +6 – 5) + (-8 +7)
F = 10 — [8 – 17+3 – (9 – 20)]
G= 12 - (-8+4 – 7) — (9 +3 – 4)
Н= 5 - 12 - (5 – 11) — (7 – 14)
Calculer à la main.
E = 26 – (-14 +6 – 5) + (-8 +7)
F = 10 — [8 – 17+3 – (9 – 20)]
G= 12 - (-8+4 – 7) — (9 +3 – 4)
Н= 5 - 12 - (5 – 11) — (7 – 14)

Bonsoir
Calculer à la main.
E = 26 – (-14 +6 – 5) + (-8 +7)
E = 26 + 14 - 6 + 5 - 8 + 7
E = 26 + 14 + 5 + 7 - 6 - 8
E = 52 - 14
E = 38
F = 10 — [8 – 17+3 – (9 – 20)]
F = 10 - (8 - 17 + 3 - 9 + 20)
F = 10 - 8 + 17 - 3 + 9 - 20
F = 10 + 17 + 9 - 8 - 3 - 20
F = 36 - 31
F = 5
G= 12 - (-8+4 – 7) — (9 +3 – 4)
G = 12 + 8 - 4 + 7 - 9 - 3 + 4
G = 12 + 8 + 7 + 4 - 4 - 9 - 3
G = 31 - 16
G = 15
Н= 5 - 12 - (5 – 11) — (7 – 14)
H = 5 - 12 - 5 + 11 - 7 + 14
H = 5 - 5 - 12 - 7 + 11 + 14
H = -19 + 25
H = 6
