  1. Giải đáp:
    a)4.52-18:2=208-9=199
    b)32.22-32.19=32(22-19)=32.3=96
    c)24.5-[131-(13-4)2]=120-(131-92)=120(131-81)=120-50=70
    d)100:{250:[450-(4.53-22.25)]}=100:{250:[450-(212-550)]}=100:[250:(450+338)]=100:(250:788)=100:125/394=315,2
    e)23.15-[115-(12-5)2]=345-(115-72)=345-66=279
    f)30.{175:[355-(135+37.5)]}=30.[175:(355-172,5)]=30.(175:162,5)=30.14/13=420/13
