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) ?

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= 660
