bonjour je dois calculer les expressions suivantes en détaillant les calculs mais je n'y arrive pas.
1-) 35 - [4 x (5+2)- 7]
2-) 12 x [32-(4+7) x 2]
3-) (1+7) x [11 - (2 + 3)]
4-) 12 + [(120 - 20) - 2 x 4 x 5]
5-) 150 - 10 - [(12 + 2) x 4 + 2]
6-) (60 - 59,9) x [30 - (25 - 15)]
Le x correspond à multiplier Merci beaucoup
