Aidez moi svpppppppppppp Exercice 1: enchainements


A = (-7) x 5+ (-2)

B = (+3) + (-4) (-3)

C = (-5) x (+3) - (-7) X (-4)

D = 7 x (-5) - (-7) X (-5)

E = (+11) X 2 x(-3) + (-15) x 2 x (-2)

F = 45-(-3) x 5 - 6 X (-8)

G = -17 - 3x (-5) - 9- (-2) X (-10)

H = 18 + (-9) + (-72) + (-9)

I = 49 - (+7) - (-42) + (-6)

J = 11 + (-35) + (+7)+4-(-21) – 3

K = -51 = (+17) + 5-(-3) = (-3)​
