$\Rightarrow 3 n - 3$ $color(blue)(=> 3n - 3$

$n - {1 - [n - (1 - n) - 1]}$ $n-{1 - [n - (1 - n) - 1]}$

$\Rightarrow n - 1 + [n - (1 - n) - 1], Removing {} bracket$ $=> n -1 + [n - (1 - n) - 1], color(red)("Removing {} bracket"$

$\Rightarrow n - 1 + n - (1 - n) - 1, Removing [] bracket$ $=> n - 1+ n - (1-n) -1, color(red)("Removing [] bracket"$

$\Rightarrow n - 1 + n - 1 + n - 1, Removing () bracket$ $=> n - 1 + n -1 + n - 1, color(red)("Removing () bracket"$

$\Rightarrow n + n + n - 1 - 1 - 1, Rearranging Like terms$ $=> n + n + n -1 -1 -1, color(red)("Rearranging Like terms"$

$\Rightarrow 3 n - 3$ $color(blue)(=> 3n - 3$

What is n−{1−[n−(1−n)−1]}n-{1-[n-(1-n)-1]}?
