    a)17+44+83+156
    =(17+83)+(44+156)
    =100+200
    =300
    b)125×103+125×19-125×22
    =125×(103+19-22)
    =125×100
    =12500
    c)1296÷9+3×17-124÷4
    =144+51-31
    =195-31
    =164

    $\text{17+44+83+156=(17+83)+(44+156)=100+200=300 }$
    $\text{125×103+125×19-125×22=125x(103+19-12)=125×100=12500}$
    $\text{1296:9+3×17-124:4=144+51-31=164}$
