Pouvez vous m'aider s'il vous plait Exercice 1 Je calcule A = −2 + 7 − 5 – 10 = B = −2 + 7 − (5 − 10) = C = 20 − 37 + 42 + 6 = D = 20 – 3 × (7+4) 2 + 6 = E = -2 × (-2) × (-2) × (-2) × (-2) = F = 100 - 50 : (- 5) = G = - 20 + 5 x (- 4) - 10 x (- 2) = H = ( 5 + 3 x (5 – 20) ) : 5 = I = 6-9x(-4) / 2+1-9=

Bonjour,

A = −2 + 7 − 5 – 10

A = 5 - 5 - 10

A = -10

__________________________________

B = −2 + 7 − (5 − 10)

B = -2 + 7 -  (-5)

B = 10

__________________________________

C = 20 − 37 + 42 + 6

C = -17 + 42 + 6

C = 31

bon courage pour la suite :)
