Answer 1

Răspuns:

a) 420-33+25×6=420-33+150=537

b) 1200-(168+24-50)×8=1200-142×8=1200-1136=64

c) 98÷2+88÷(19-15)=49+88÷4=49+22=71

d) (344+108-252)-(190+10-60)=200-140=60

e) 90-10+810=80+810=890

f) 734-11-(8-6)×3=734-11-2×3=734-11-6=723-6=717

g) 100÷10-(9-8+7)÷4=10-8÷4=10-2=8

h) (8+4+246)×2=258×2=516

i) (860-810)÷5+654-24÷6=50÷5+654-4=10+654-4=664-4=
