VA ROG AJUTAȚI MA DAU COROANĂ

Answer 1

200:10+2×3×10=20+60=80

245×11×10-200=2695×10-200=26950-200=
=26750

273-73:2+2×4×36-400=273-36.5+288-400=
=561-400-36.5=61-36.5=34.5

20+30:10+2×7=20+3+14=37

a+7=17 rezulta a=17-7=10

a-3=14 rezulta a=14+3=17

a-5=15 rezulta a=15+5=20

10-a=3 rezulta a=10-3=7

2 {40:10+2 [3×3+10×(700-100)]}=
=2 {4+2 [9+10×600]}=
=2 (4+2×6009)=
=2×12022=
=24044

(225:5)×2+4 [400-300-10×10]+4=
=45×2+4 [100-100]+4=
=90+4×0+4=
=94
Sper ca te-am ajutat
