    a) 16.83+16.17
    =16.(83+17)
    =16.100
    =1600
    b)50-[(20-2^3):2+34]
    =50-(10-2^2+34)
    =50-(10-2^2+34)
    =50-(10-4+34)
    =50-10+4-34
    =(50-10)-(34-4)
    =40-30
    =10
    c)-219+19+(-100)
    =(-219-100)+19
    =-319+19
    =-300

    $\text{a) 16. 83 + 16. 17}$
    $\text{= 16. ( 83 + 17 )}$
    $\text{= 16. 100}$
    $\text{= 1600}$
    $\text{b) 50 – [ ( 20 – 2³ ) : 2 + 34 ]}$
    $\text{= 50 – [ ( 20 – 8 ) : 2 + 34 ]}$
    $\text{= 50 – ( 12 : 2 + 34 )}$
    $\text{= 50 – ( 6 + 34 )}$
    $\text{= 50 – 40}$
    $\text{= 10}$
    $\text{c) -219 + 19 + ( -100 )}$
    $\text{= -200 + ( -100 )}$
    $\text{= -300}$
