Bonjour,
Calculer astucieusement les produits suivants
a) −1,5×2,5×(−4)
= - 1,5 x (- 10)
= 15
b) −25×0,135×(−4)×(−0,2)×50
= - 25 x (- 4) x (-0,2) x 50 x 0,135
= 100 x (- 10) x 0,135
= - 1000 x 0,135
= - 135
c) −0,5×0,25×(−20)×40×(−4,16)
= 0,25 x 40 x (- 0,5) x (- 20) x (- 4,16)
= 10 x 10 x (- 4,16)
= 100 x (- 4,16)
= - 416
