    $\text{1) 35 + (- 7).9 + 201 – 135 + 63}$
    = $\text{35 – 63 + 201 – 135 + 63}$
    = $\text{(- 63 + 63) + (35 – 135) + 201}$
    = $\text{- 100 + 201}$
    = 101
    $\text{2) – 329 + (115 – 101) – (15 – 440)}$
    = $\text{- 329 + 115 – 101 – 15 + 440}$
    = $\text{(- 329 – 101) + (115 + 15) + 440}$
    = $\text{- 430 + 130 + 440}$
    = $\text{- 300 + 440}$
    = $\text{140}$

    35 + (-7) . 9 + 201 – 135 + 63
    = 35 – 7 . 9 + 201 – 135 + 63
    = 35 – 63 + 201 – 135 + 63
    = -28 + 201 – 135 + 63
    = 101
    —————————————-
    -329 + (115 – 101) – (15 – 440)
    = -329 + 14 – (-425)
    = (-329) + 14 + 425
    = -315 + 425
    = 110
