Răspuns:
d)60
e)890
f)717
h)522
Explicație pas cu pas:
d) (8×43+9×12-7×36)-(190+70÷7-12×5)=
=(344+108-252)-(190+10-60)=
=(452-252)-(200-60)=
=200-140=60
e) 90-90÷9+90×9=
=90-10+810=80+810=890
f) 734-22÷2-(40÷5-2×3)×3=
734-22÷2-(8-6)×3=
=734-22÷2-2×3=
=734-11-6=723-6=717
h) (32÷4+12÷3+82×3)×2=
=(8+4+246)×2=
=(12+246)×2=
=258×2=516
