Question

Rezolva [2400-75×(96:3:2)]×235= 1000-[(250:25+330:3)-(30×2-5×8)]×4=
(220:4+6)×100-[25+(299-77×3)]+12= [700-(505-135×2-38×3)×2]-100=

Answer 1

[2400-75×(32:2)]×235=
(2400-75×16)×235=
(2400-1200)×235=
1200×235=282000

1000-[(10+110)-(60-40)]×4=
1000-(120-20)×4=
1000-100×4=
900×4=3600

(220:4+6)×100-[25+(299-231)]+12=
(220:4+6)×100-(25+68)+12=
(55+6)×100-93+12=
58×100-93+12=
5800-93+12
5707+12=5719

[700-(505-270-114)×2]-100=
[700-(235-114)×2]-100=
(700-121×2) - 100=
(700-242)-100=
458-100=358
