    (123+345)+(456-123)-[2017-(-345)]
    =123+345+456-123-2017-345
    =(123-123)+(345-345)-(2017-456)
    =0+0-1561
    =0-1561
    =-1561

    $\text{(123 + 345) + (456 – 123) – [2017 – (-345)]}$
    $\text{= (123 + 345) + (456 – 123) – (2017 + 345)}$
    $\text{= 123 + 345 + 456 – 123 – 2017 – 345}$
    $\text{= (123 – 123) + (345 – 345) + (456 – 2017)}$
    $\text{= -1561}$
