n - {1 - [n - (1 - n) - 1]}          first you do - (1 - n)  [multiply -1 to 1 - n)

n - {1 - [n - 1 + n - 1]}

n - {1 - [n + n - 1 - 1]}

n - {1 - [2n - 2]}                 you do - (2n - 2)  [multiply -1 to 2n - 2)

n - {1 -2n + 2}

n - {-2n + 3}                     you do - (-2n + 3)  [multiply -1 to -2n + 3)

n + 2n - 3
