bonjour
ta calculatrice peut te le dire
D = - 14 - 6 - ( - 3 )
= - 14 - 6 + 3
= - 17
E = ( - 17 ) x ( 9 + 5 )
= - 17 x 14
= - 238
F = 9 x ( - 8 ) / - 14 : 7
= - 72 / - 2
= 36
D=-7×2+24÷(-4)-(6-9)
=-14-6-(-3)
=-20+3
=-17
E=(25-42)×(9-15÷(-3))
=-17×(9+5)
=-17×14
=-238
F=9×(35-43)/(-8-6)÷7
=9×(-8) /(-14)÷7
=-72/-2
=36
