Calculer les expressions suivantes en respectant toutes les règles ! (opérations prioritaires et règle des signes)
A = 5 x (-2) - (-50) ÷ 10

B = (-4) x (-5) x (-2) - (+12) ÷ (-3) - 3

C = (1 - 2 x 3) - (-7 +5 - 3)​

A = 5×(-2)-(-50)÷10

A = -10-(-50)÷10

A = -10+50÷10

A = -10+5

A = -5

B = (-4)×(-5)×(-2)-(+12)÷(-3)-3

B = -40-12÷(-3)-3

B = -40+4-3

B = -39

C = (1-2×3)-(-7+5-3)

C = (1-6)-(-7+5-3)

C = (1-6)-(-5)

C = (-5)-(-5)

C = 0
